Reaction Steps

The solution of N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)-3-(piperazin-1-ylmethyl)benzamide (78 mg, 0.19 mmol) and HCHO solution (0.5 mL) in MeOH (10 mL) was stirred at 27° C. for 1 h. Then NaBH3CN (14.5 mg, 0.23 mmol) was added to the solution and stirred at 27° C. for 4 h. The solution was concentrated and the residue was purified by column chromatography to give the title product (14.1 mg, Yield 17.5%). 1H NMR (CD3OD, 400 MHz): δ 7.79 (s, 1H), 7.70 (d, J=7.8 Hz, 1H), 7.50 (d, J=7.5 Hz, 1H), 7.39-7.32 (m, 1H), 7.20-7.07 (m, 3H), 7.06-6.98 (m, 1H), 4.13 (quin, J=6.0 Hz, 1H), 3.75 (s, 2H), 3.63-3.44 (m, 4H), 2.95-2.83 (m, 4H), 2.78-2.62 (m, 3H), 2.62-2.30 (m, 7H), 2.28 (s, 3H). LCMS (m/z): 423.2 (M+1).
