実験手順

To a stirred solution of 6.9 grams of 4,6-dichloro-2-diethylamino-5-pyrimidinecarbonitrile in 80 ml of acetone was added dropwise 3.2 grams of cyclopropylamine in 20 ml of acetone. The reaction mixture stood for 16 hours; then the acetone was removed by evaporation under reduced pressure. The residue was washed with water, and the resultant solid was collected. The solid was washed several times with water, then dried, to give 6.5 grams of crude product; mp, 100°-105°. The crude product was recrystallized from petroleum ether to give 2.5 grams of 4-chloro-6-cyclopropylamino-2-diethylamino-5-pyrimidinecarbonitrile; mp, 120°-122°.
