実験手順

To a solution of (R)-4-nitrophenyl 1-(4-(trifluoromethyl)phenyl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (70 mg, 158 μmol, example 88) in MeCN (0.5 mL) was added 4-amino-2-fluorobenzonitrile (65 mg, 475 μmol). The resulting mixture was then subjected to a microwave irradiation at 180° C. for 15 min. Then, sodium hydride, 60% dispersion in mineral oil (22 μL, 475 μmol) was added and the mixture was stirred at RT for overnight. Then, H2O (0.5 mL) was added and the solvents were removed. The residue was then dissolved in a solution of MeOH and DMSO (1:1, 1.0 mL). The solution mixture was then purified by preparative HPLC (0%-100% MeCN 0.1% TFA/H2O 0.1% TFA) to give the desired product, which was then dissolved in MeOH (1.0 mL). The solution was then washed through PL-HCO3 MP resin (polymerlabs, 200 mg/6 mL tube) and the resin was washed with MeOH (2×0.5 mL). The combined washings were then concentrated and dried under vacuum to give the title compound as a yellow solid. MS (ESI, positive ion) m/z: 440 (M+H).
