HCID 780104,5-Pyrimidinediamine, 6-chloro-

Conditions

Temperature: 118 °C

Procedure

A suspension of 5-Amino-4,6-dichloropyrimidine (3 g, 0.02 mol) in ammonia (25 mL, 7N/MeOH, 0.175 mole) was heated at 118° C. overnight(under pressure). The reaction was cooled to 23° C., filtered and washed with ethanol to obtain 1.92 g (70%).
