実験手順

To a solution of N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)-3-(pyrrolidin-2-yl)benzamide (20 mg, 0.13 mmol) in MeOH (20 mL) was added HCHO (1 mL) and AcOH (0.05 mL). The reaction mixture was stirred at room temperature for 30 min at which time NaBH3CN (200 mg, 3.22 mmol) was added. The reaction mixture was stirred at room temperature for 2 h. The solvent was removed and the crude product was purified by prep-HPLC to give the desired product (8.5 mg, Yield 16.8%). 1H NMR (CD3OD, 400 MHz): δ 7.80 (brs, 1H), 7.67 (d, J=7.6 Hz, 1H), 7.52 (d, J=7.6 Hz, 1H), 7.35-7.41 (m, 1H), 7.09-7.15 (m, 3H), 7.09-7.15 (m, 1H), 7.02-7.08 (m, 1H), 4.10-4.16 (m, 1H), 3.73-3.81 (m, 2H), 3.49-3.58 (m, 2H), 3.20-3.28 (m, 1H), 3.08-3.16 (m, 1H), 2.84-2.97 (m, 4H), 2.64-2.75 (m, 2H), 2.33-2.40 (m, 1H), 2.20-2.27 (m, 1H), 2.16 (s, 3H), 1.95-2.05 (m, 1H), 1.77-1.93 (m, 2H). LCMS (m/z): 394.1 (M+1).
