Abstract

1364917 1 H-Tetrazoles FUJISAWA PHARMACEUTICAL CO Ltd 22 Sept 1971 44199/71 Heading C2C 1H-Tetrazoles of Formula I: wherein each of R and R<SP>1</SP> is hydrogen; or an unsubstituted C 1-6 alkyl group; a phenyl, tolyl, xylyl, mesityl, naphthyl, biphenylyl, benzyl, tolylmethyl, xylylmethyl, phenethyl, tolylethy, α-methylbenzyl or α-methylphenethyl group; or a C 1-6 alkyl group substituted by a halogen atom or by a carboxyl, C 2-7 alkoxycarbonyl, benzyloxycarbonyl, tolylmethyloxycarbonyl, xylylmethoxycarbonyl, phenethoxycarbonyl, tolylethoxycarbonyl, α - methylbenzyloxycarbonyl, α - methylphenethoxycarbonyl, carbamoyl, hydroxy, amino, methylamino, ethylamino, propylamino, isopropylamino, dimethylamino, diethylamino, dipropylamino, methylethylamino, or C 1-4 alkoxy group, are prepared by reacting a compound of formula RNH 2 , or a salt thereof with a hydrazoic acid salt and an orthocarboxylic acid ester of formula R<SP>1</SP>C(OR<SP>2</SP>) 3 , wherein R<SP>2</SP> is a C 1-6 alkyl group. The reaction is preferably carried out in a solvent inert under the reaction conditions, e.g. acetic acid, propionic acid, an alcohol or dimethylformamide, and with heating. The examples prepare tetrazoles of Formula I wherein R and R<SP>1</SP> are respectively, phenyl and hydrogen, hydrogen and hydrogen, -CH 2 CO 2 H and -CH 3 , -CH 2 CO 2 H and hydrogen, -CH 2 CO 2 C 2 H 5 and hydrogen, and -C(CH 3 ) 2 - CH 2 OH and hydrogen.
