Reaction Steps

Polymer supported 1,3-dicyclohexylcarbodiimide (0.845 g) in dichloromethane (5 mL) was treated with 5-isoquinolinylacetic acid (0.075 g, 0.40 mmol) in dichloromethane (1 mL), 1-hydroxy-7-azabenzotriazole (0.049 g), and triethylamine (0.080 g) in dichloromethane (1 mL). After stirring for 5 minutes, the mixture was treated with 4-(trifluoromethoxy)benzylamine (0.40 mmol). After stirring for 16 hours, the mixture was treated with MP-Carbonate resin (0.310 g), stirred for 5 minutes, and filtered. The filtrate was diluted with dichloromethane (40 mL), washed with water (4×20 mL), brine (1×20 mL), dried (Na5SO4), filtered, and the filtrate was concentrated under reduced pressure to provide the title compound which was purified by forming the hydrochloride salt and triturating the solid with hot ethyl acetate.
