Reaction Steps

A solution of 3-amino-N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)benzamide (130 mg, 0.4 mmol), 2,2-dimethyldihydro-2H-pyran-4(3H)-one (52 mg, 0.4 mmol) and AcOH (0.1 mL) in MeOH (10 mL). The mixture was stirred at 22° C. for 12 h, then NaBH3CN (76 mg, 1.2 mmol) was added and the resulting mixture was stirred at 22° C. for 2 h. The reaction mixture was concentrated and quenched with water. The aqueous mixture was extracted with DCM, the combined organic layers were concentrated and the residue was purified by prep-HPLC to give the title compound (5.5 mg, Yield 3.1%). 1H NMR (CD3OD, 400 MHz): δ 8.42 (brs, 1H) 7.00-7.33 (m, 7H) 6.84 (d, J=7.8 Hz, 1H) 4.21-4.41 (m, 3H) 3.40-3.92 (m, 8H) 3.11-3.20 (m, 3H) 1.91-2.07 (m, 2H) 1.18-1.44 (m, 8H). LCMS (m/z): 438.3 (M+1).
