Procedure

A 7N ammonia in methanol solution (75 ml) was added to 6-chloro-4-(1H-6-indolylamino)pyrimidine (1.229 g, 5.0 mmol); and the reaction mixture was heated in a sealed tube at 130° C. for 6 days. The solvent was distilled off under reduced pressure; the residue was purified by silica gel column chromatography (eluent; ethyl acetate:tetrahydrofuran=1:1); diethyl ether was added to the residue to crystallize; the crystals were filtered off, and washed with diethyl ether, and dried under aeration to yield the title compound (883 mg, 3.9 mmol, 78%) as pale yellow crystals.
