Reaction Steps
To a solution of 3-amino-N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)benzamide (100 mg, 0.31 mmol) in MeOH (5 mL) was added AcOH (0.05 mL) and oxetan-3-one (22 mg, 0.31 mmol). The mixture was stirred at 22° C. for 2 h. NaBH3CN (98 mg, 1.55 mmol) was added, and the resulting mixture was stirred at 22° C. for 2 h. The reaction solution was concentrated, the residue was washed with water, extracted with EA, the organic layer was concentrated, and the residue was purified by prep-HPLC to give the title compound (17 mg, Yield 14.4%). 1H NMR (CD3OD, 400 MHz): δ 7.17-6.97 (m, 6H), 6.96-6.88 (m, 1H), 6.72-6.62 (m, 1H), 5.03-4.95 (m, 2H), 4.67-4.59 (m, 1H), 4.59-4.49 (m, 2H), 4.15-4.04 (m, 1H), 3.80-3.69 (m, 2H), 3.56-3.40 (m, 2H), 2.96-2.79 (m, 4H), 2.73-2.58 (m, 2H). LCMS (m/z): 382.2 (M+1).
