Reaktionsschritte

To a solution of (R)-1-(4-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydroisoquinoline (80 mg, 0.29 mmol) in MeCN (2 mL) was added 4-nitrophenyl 4,4-difluoro-cyclohexylcarbamate (217 mg, 0.72 mmol). The resulting mixture was then subjected to microwave irradiation at 120° C. for 15 min. Then, MeOH (0.5 mL) was added and the mixture was filtered. The filtrate was purified by preparative HPLC (0%-100% MeCN 0.1% TFA/H2O 0.1% TFA) to give the title compound, which was dissolved in MeOH (1 mL). The solution was then passed through PL-HCO3 and the resin was washed with MeOH (2×0.3 mL). The combined filtrates were concentrated and dried in vacuo to give the title compound as a light-yellow solid. MS (ESI, positive ion) m/z: 439 (M+H).
