Assignee:
Merck & Co., Inc. - Rahway NJ
International Classification:
C07D265/18
US Classification:
544 92
Abstract:
The instant invention describes a method for crystallizing (−)-6-chloro-4-cyclopropylethynyl-4-trifluoromethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one from a solvent and anti-solvent solvent system and producing the crystalline product. The desired final crystal form, Form I, can be produced when using methanol or ethanol. Form II is isolated from 2-propanol and can be converted to the desired crystal form at low drying temperatures, such as between about a temperature of 40 C. and 50 C.
