Reaction Steps

A neat mixture of tert-butyl 3-(6-chloropyrimidin-4-ylamino)pyrrolidin-1-carboxylate (354 mg, 1.18 mmol) and 3-chloro-4-fluoroaniline (3.03 g, 20.8 mmol) was heated at 140° C. for 21 hours. Upon cooling to ambient temperature, the melt was diluted with EtOAc and the mixture was stirred for 1 hour. A beige, amorphous precipitate was collected, washed with water and dried in vacuo at 50-60° C. giving 292 mg (80%) of N4-(3-chloro-4-fluorophenyl)-N6-(pyrrolidin-3-yl)pyrimidine-4,6-diamine. MS (APCI): (M+1)=308, (M−1)=306.
