Procedure

Methyl 2-(2-chloro-4-methyl-6-p-tolylpyrimidin-5-yl)pentanoate (100 mg; 0.300 mmol), and benzylamine (0.164 mL; 1.502 mmol) were placed in a 2 mL reaction tube and dissolved in isopropanol (1.5 mL). The tube was sealed and irradiated in a microwave oven at 180° C. for 1 h. The reaction mixture was partitioned between brine and dichloromethane, filtered over a phase separator filter (1PS) and concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel using a linear gradient of ethylacetate (5-40%) in heptane to give 55 mg (33%) of the title compound as a colorless oil.
