Abstract:
PROBLEM TO BE SOLVED: To provide a novel crystalline polymorphous form of ritonavir and a process for producing the same. SOLUTION: There is provided a substantially pure crystalline polymorphous form of (2S, 3S, 5S)-5-(N-(N-((N-methyl-N-((2-isopropyl-4-thiazoyl)methyl)amino)carbonyl)-L-valinyl)amino)-2-(N-((5-thiazolyl)methoxycarbonyl)amino)-1,6-diphenyl-3-hydroxyhexane which gives peaks of 2θ angle at 8.67°±0.1°, 9.88°±0.1°, 16.11°±0.1°, 16.70°±0.1°, 17.36°±0.1°, 17.78°±0.1°, 18.40°±0.1°, 18.93°±0.1°, 20.07°±0.1°, 20.65°±0.1°, 21.71°±0.1° and 25.38°±0.1° in a powder X-ray diffraction pattern. There is also provided a process for producing the crystalline polymorph form, which includes inoculating seed crystals in a solution of ritonavir, and then adding an anti-solvent.
