Reaction Steps

To a solution of 4-bromo-6-methoxyisoquinolin-1(2H)-one (0.5 g, 1.968 mmol) and tert-butyl piperazine-1-carboxylate (0.916 g, 4.92 mmol) in ethylene glycol (5 ml) was added DIPEA (1.0.31 ml, 5.90 mmol) and heated to 145° C. for overnight in sealed tube. The reaction mixture was diluted with water and extracted with ethyl acetate. Combined organic layer was dried over anhydrous sodium sulfate, filtered and evaporated to get crude compound (0.3 g, 29.4%). The crude compound was taken for the next step without further purification. MS: MS m/z 260.20 (M++1).
