Procedure

1.6 g (6.9 mmol) 4-chloro-6-cyclopropylpyrimidine [FR 1 519 069 (1966); Chem. Abstr. 71, 49965y, 1969] and 3.4 ml (3.5 g, 69.0 mmol) hydrazine hydrate are stirred at a bath temperature of 90° C. for 16 h. Ethylene glycol monoethyl ether is added to the cooled reaction mixture and the mixture is concentrated in vacuo. This operation is repeated once. The residue is then chromatographed over silica gel 60 (mobile phase: acetonitrile/water 8:2).
