Reaction Steps

A solution of 4-chloro-2-(2-methoxyphenyl)thieno[3,2-d]pyrimidine (0.15 g, 0.54 mmol), isobutyl piperazine-1-carboxylate (0.10 g, 0.54 mmol), and Et3N (0.15 mL, 1.1 mmol) in DMF (1.8 mL) was heated in a microwave oven at 180° C. for 5 min. The reaction was cooled and diluted with CH2Cl2. The solution was washed with water, dried over Na2SO4, and concentrated under vacuum to give isobutyl 4-(2-(2-methoxyphenyl)thieno[3,2-d]pyrimidin-4-yl)piperazine-1-carboxylate (0.11 g, 55% yield). LC/MS: m/z 427.5 (M+H)+ at 2.58 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
