Procedure

4-Chloro-6-cyclopropylamino-2-(1-methylpropylamino)-5-pyrimidinecarbonitrile was prepared by the method of Example XVII, substituting 4,6-dichloro-2-(1-methylpropylamino)-5-pyrimidinecarbonitrile and cyclopropylamine for 4,6-dichloro-2-ethylamino-5-pyrimidinecarbonitrile and isopropylamine. The reaction product was recrystallized from methylcyclohexane to give 4-chloro-6-cyclopropylamino-2-(1-methylpropylamino)-5-pyrimidinecarbonitrile; mp, 112°-114°.
