To a stirred mixture of 1B (0.5 g, 1.93 mmol) and N-(2-vinyl-phenyl)-acetamide bb (0.314 g, 1.95 mmol) in DMF (5 mL) was added NaH (47 mg, 1.95 mmol) at 0° C. The reaction mixture was stirred for 30 minutes at room temperature, then poured into H2O (50 mL) and extracted with Et2O (20 mL). The Et2O layer was washed with H2O (2×20 mL), dried (MgSO4), filtered and concentrated in vacuo to give 1C (0.63 g, 96%). HPLC Rt=3.212 min. (Column: YMC ODS-A 4.6×50 mm (4 min.); Solvent A=10% MeOH, 90% H2O, 0.1% TFA; Solvent B=90% MeOH, 10% H2O, 0.1% TFA).
