Abstract

Un proceso para preparar forma 1 de Efavirenz cristalino, donde el proceso comprende: 1) cristalizar la forma 4 de Efavirenz cristalino a partir de una solucion de THF/heptano donde la solucion de THF/heptano presenta una concentracion de aproximadamente 5% de THF y se reduce a una concentracion de alrededor de 1% de THF y 2) calentar la forma 4 de Efavirenz cristalino a una temperatura de aproximadamente 80°C a aproximadamente 100°C. Reivindicacion 2: Un proceso para preparar la forma 1 de Efavirenz cristalino, caracterizado porque presenta un patron de difraccion de partículas por rayos X que comprende cuatro o más valores seleccionados del grupo formado por: 6,0 +- 0,2; 6,3 +- 0,2; 10,3 +- 0,2; 10,8 +- 0,2; 14,1 +- 0,2; 16,8 +- 0,2; 20,0 +- 0,2; 20,5 +- 0,2; 21,1 +- 0,2; y 24,8 +- 0,2, donde el proceso comprende: 1) cristalizar la forma 4 de Efavirenz cristalino a partir de una solucion de THF/heptano donde la solucion de THF/heptano presenta una concentracion de aproximadamente 5% de THF y se reduce a una concentracion de alrededor de 1% de THF y 2) calentar la forma 4 de Efavirenz cristalino a una temperatura de aproximadamente 80°C a aproximadamente 100°C. Reivindicacion 3: Un proceso para preparar la forma 1 de Efavirenz cristalino, caracterizado porque presenta un termograma de calorimetría diferencial de barrido que presenta un pico en aproximadamente 138sC a 140°C, donde el proceso comprende: 1) cristalizar la forma 4 de Efavirenz cristalino a partir de una solucion de THF/heptano donde la solucion de THF/heptano presenta una concentracion de aproximadamente 5% de THF y se reduce a una concentracion de alrededor de 1% de THF y 2) calentar la forma 4 de Efavirenz cristalino a una temperatura de aproximadamente 80°C a aproximadamente 100°C.
