Reaction Steps

A mixture of ethyl 4-({(1-bromo-4-methylisoquinolin-3-yl)[4-(trifluoromethoxy)-benzyl]amino}sulfonyl)benzoate (93.5 mg, 0.15 mmol) prepared in Example 9-(1), pyrrolidine (0.015 mL, 0.18 mmol), 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (9.3 mg, 0.015 mmol), trisdibenzylideneacetone dipalladium (6.9 mg, 0.0075 mmol) and sodium-t-butoxide (20.2 mg, 0.21 mmol) in toluene (2 mL) was stirred at 100° C. for 4 hours under argon atmosphere. The mixture was cooled to room temperature, and then filtered, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane=10%→25%) to give ethyl 4-({(4-methyl-1-pyrrolidin-1-ylisoquinolin-3-yl) [4-(trifluoromethoxy)benzyl]amino}sulfonyl)benzoate (22.4 mg, 24%) as a yellow viscous material.
