The present invention provides novel solvated forms of darunavir and processes for their preparation. The present invention also provides novel processes for the preparation of darunavir amorphous form and pharmaceutical compositions comprising it. Thus, for example, darunavir 2-methyl-2-butanol solvate was dissolved in methylene dichloride, distilled under vacuum at 45° C. to obtain a residue, cyclohexane was added to the residue and stirred for 30 hours at 20 to 25° C., and the separated solid was filtered, washed with cyclohexane and dried under vacuum at 50° C. for 12 hours to yield darunavir amorphous form.
本发明提供了达芦那韦的新型溶剂形式以及其制备方法。本发明还提供了制备达芦那韦非晶态形式和含有达芦那韦的制药组合物的新型方法。例如,将达芦那韦2-甲基-2-丁醇溶剂加入二氯甲烷中,在45°C下真空蒸馏得到残渣,加入环己烷并在20至25°C下搅拌30小时,分离出固体后用环己烷洗涤并在50°C下真空干燥12小时,即可得到达芦那韦非晶态形式。
