実験手順
To a solution of (1R,3S)-1-(4-chlorophenyl)-3-methyl-1,2,3,4-tetrahydroisoquinoline (60 mg, 233 μmol) in CH2Cl2 (1.0 mL) at RT was added 1-fluoro-4-isocyanatobenzene (42 μL, 361 μmol). The reaction was stirred 4 h and directly purified by reverse phase HPLC to give (1R,3S)-1-(4-chlorophenyl)-N-(4-fluorophenyl)-3-methyl-3,4-dihydroisoquinoline-2(1H)-carboxamide as a light purple solid. MS (ESI pos. ion) m/z: 395 (M+1).
