Procedure
A mixture of 5-tert-butyloxycarbonylamino-6-methyl-2-phenyl-4-(4-pyridyl)pyrimidine (1.5 g) and an isopropanol solution of hydrogen chloride (4 ml, HCl 5 mMol/ml) in ethanol (15 ml) was stirred for 1 hour at 40° C. After cooling to room temperature, the reaction mixture was poured into a suspension of ethyl acetate (100 ml) and water (50 ml) under stirring, and the mixture was adjusted to pH 9.0. The separated organic layer was washed with saturated aqueous sodium chloride and dried over magnesium sulfate. The solvent was evaporated in vacuo, and the residual crystal was recrystallized from ether to give 5-amino-6-methyl-2-phenyl-4-(4-pyridyl)pyrimidine, mp 208°-209° C.
