Me2NC(:NH)NH2.0.5H2SO4 (91 g.), stirred 30 min. with 300 cc. boiling MeOH containing 15 g. Na, the solution treated with 116 g. CH2(CO2Et)2, refluxed 6 hrs., diluted with 450 cc. H2O, and acidified with AcOH, gives 85 g. 2-dimethylamino-4,6-dihydroxypyrimidine (I), with 3 mols. H2O, does not m. at 350°. I (15.5 g.) and 60 cc.POCl3, refluxed 35 min. and poured into 1 l. cold 2 N NaOH, give 16 g. 4,6-dichloro-2-dimethylaminopyrimidine (II), m. 54°; II also results from the reaction of 2,4,6-tri-chloropyrimidine and Me2NH on crystallization from petr. ether and aqueous MeOH (cf. King and King, C.A. 42, 1280h). I (3.8 g.) and 10 cc. 10% EtOH-NH3, heated 18 hrs. at 110-20°, give 4-amino-6-chloro-2-dimethylaminopyrimidine, m. 151°; this results also from 4-amino-2,6-dichloropyrimidine and Me2NH (10 hrs. at 80°). I and EtOH-MeNH2 or 2,4-dichloro-6-methylaminopyrimidine and alc. Me2NH give 4-chloro-2-dimethylamino-6-aminopyrimidine, b1 122-5°. Il and EtOH-Me2NH give 4-chloro-2,6-bis(dimethylamino)-pyrimidine, m. 52.2°, sublimes 56°/0.1 mm.
