Reaction Steps
To a solution of 3-amino-N-(2-hydroxy-3-(isoindolin-2-yl)propyl)benzamide (120 mg, 0.39 mmol) in MeOH (10 mL) was added dihydro-2H-pyran-4(3H)-one (78 mg, 0.78 mmol) and AcOH (0.05 mL). The mixture was stirred at 25° C. for 2 h. NaBH3CN (123 mg, 1.95 mmol) was added, and the resulting mixture was stirred at 25° C. for 16 h. The reaction mixture was concentrated, and the residue was dissolved in water, extracted with ethyl acetate, dried over sodium sulfate and concentrated. The crude product was purified by preparative HPLC purification. (22 mg, yield 14%) MS (ESI+) e/z: 396.2 [M+1]+. 1H NMR (MeOD, 400 MHz), δ ppm: 7.62-7.53 (m, 2H), 7.53-7.36 (m, 5H), 7.30-7.21 (m, 1H), 4.76-4.57 (m, 2H), 4.34-4.24 (m, 1H), 4.08-3.96 (m, 2H), 3.74-3.65 (m, 1H), 3.65-3.57 (m, 2H), 3.57-3.43 (m, 4H), 3.36-3.32 (m, 2H), 2.03-1.91 (m, 2H), 1.72-1.57 (m, 2H).
