Procedure

Benzylamine (1.2 mL, 11 mmol), 120b (1.0 g, 3.6 mmol), water (50 mL), and acetone (50 mL) were heated an reflux for 28 h, then stirred at room temperature an additional 41 h. After evaporation of the acetone, the mixture was extracted with EtOAc (2×). The organic phase was extracted further with water and brine, then dried (Na2SO4), filtered and concentrated. The product was purified by chromatography on silica gel, eluting with 30% to 50% EtOAc in hexanes, then evaporated to yield a yellow oil (0.57 g). IR(neat): cm-1 1722. 1H NMR(300 MHz, CDCl3): 7.57-7.08 (m, 9H), 3.88 (s, 3H), 3.56 (s, 2H), 3.24 (m, 4H), 2.61 (m, 4H). HR-MS: Calc'd. 311.1760, Found 311.1764.
