Title: Crystals of N- (trans-4-isopropylcyclohexlycarbonyl)-D-phenylalanine and methods for preparing them
Abstract:Stable crystals of N-(trans-4-isopropylcyclohexylcarbonyl)-D-phenylalanine may be produced by treating this compound with a solvent at a temperature of at least 10.degree. C. and forming crystals in the solvent at a temperature of at least 10.degree. C. For example, crystals may be formed by crystallization out of solution, or may be formed from solid particles of the compound suspended in a solvent. Crystals formed in this way have different melting point, infra red spectrum and X-ray diffraction patterns from previously known forms of the compound and have enhanced processability, e.g., stability to grinding.
