    摘要: The instant invention describes a method for crystallizing (null)-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 40null C. and 50null C.

    摘要: A method for preparing a desired benzoxazine compound comprises preparing a substantially homogeneous reaction mixture that includes a phenolic compound; a primary amine; and an aldehyde, but no solvent other than for the solvency which the reactants may have for each other. Following its preparation, the reaction mixture is maintained at a temperature, and for a period sufficient to cause the reactants to combine chemically to form the desired compound.
