Abstract
PROCESSOS PARA A PREPARAÇÃO DE UM COMPOSTO DE PIRIDONA, E PARA A PREPARAÇÃO DE UMA FORMA CRISTALINA, COMPOSTO, SAL OU UM HIDRATO DESTE, FORMA CRISTALINA DE UM SAL DE SÓDIO OU UM HIDRATO DESTE, E, COMPOSIÇÃO FARMACÊUTICA. Um método de síntese que fornece uma ligação de anel inicial por intermédio de uma bromação do composto I-I produzindo o composto II-II, por meio do qual um produto final tal como AA pode ser sintetizado. Em particular, a cadeia lateral contendo 2,4-difluorofenila é ligada antes da criação do anel Q adicional.PROCESSES FOR PREPARING A PYRIDONE COMPOUND, AND FOR PREPARING A CRYSTALLINE FORM, COMPOUND, SALT OR A HYDRATE THEREOF, CRYSTALLINE FORM OF A SODIUM SALT OR A HYDRATE THEREOF, AND, PHARMACEUTICAL COMPOSITION. A synthetic method that provides an initial ring linkage via a bromination of compound I-I producing compound II-II, whereby a final product such as AA can be synthesized. In particular, the 2,4-difluorophenyl-containing side chain is attached prior to the creation of the additional Q ring.
Description
[001] A presente invenção compreende modificações de processospara sintetizar os compostos tendo Atividade inibidora do HIV integrase.[001] The present invention comprises modifications of processes for synthesizing compounds having HIV integrase inhibitory activity.
[002] A WO 2006/116764 publicada em 2 de novembro de 2006,incorporada por referência em sua totalidade, descreve vários compostos e esquemas sintéticos detalhados para a sua preparação. Em particular, uma sequência de reação é representada na página 79 desta em que 3-benzilóxi-2- metil-1H-piridina-4-ona da fórmula 3 é aí tratada com bromo para a bromopiridina 4 aí, que é depois reagida com metanol e monóxido de carbono para produzir o éster metílico do ácido nicotínico 5 aí que é depois de diversas etapas reagido com uma benzilamina para criar a piridina 10 contendo cadeia lateral de amida. Assim, a cadeia lateral de amida está no lugar antes da criação do anel Z1Z2 do produto final da fórmula (I) nesse ponto na reação representada na página 80 de 16 a 17-1.[002] WO 2006/116764 published 2 November 2006, incorporated by reference in its entirety, describes several compounds and detailed synthetic schemes for their preparation. In particular, a reaction sequence is depicted on page 79 thereof in which 3-benzyloxy-2-methyl-1H-pyridine-4-one of formula 3 is treated therein with bromine to the bromopyridine 4 therein, which is then reacted with methanol and carbon monoxide to produce the nicotinic acid methyl ester 5 therein which is then subsequently reacted with a benzylamine to create the amide side chain-containing pyridine 10. Thus, the amide side chain is in place prior to the creation of the Z1Z2 ring of the final product of formula (I) at that point in the reaction depicted on page 80 from 16 to 17-1.
