Procedure
To a solution of the product of Step A (21.6 mg, 0.05 mmol), NEt3 (21 μL, 0.15 mmol), and catalytic amount of DMAP in 10 mL of CH2Cl2 at rt was added benzoyl chloride (11.5 μL, 0.10 mmol). After stirring for 2 h, the reaction was quenched by adding saturated aq NaHCO3 (5 mL) and the resulting mixture was stirred at rt for 30 min. The reaction mixture was partitioned between CH2Cl2 (50 mL) and saturated aq NaHCO3 (50 mL). The aq layer was separated and extracted with CH2Cl2 (3×10 mL). The organic layers were combined, dried over MgSO4, and concentrated. Chromatography on Biotage 40+S cartridges using 3:17 v/v EtOAc/hexanes as the eluant afforded the title compound: 1H NMR δ 1.57 (s, 3H), 1.65 (s, 3H), 2.24 (dd, J=6.7, 14.2, 1H), 2.46 (dd, J=5.9, 14.3, 1H), 6.40 (t, J=6.2, 1H), 7.00 (d, J=8.4, 2H), 7.16-7.28 (m, 5H), 7.45-7.60 (m, 3H), 7.77 (s, 1H), 8.07 (d, J=7.5, 2H).
