Reaction Steps

Compound 9a (36 mg, 0.087 mmol) was dissolved in dichloromethane (5 ml) followed by triethylamine (44 mg, 0.44 mmol). Methanesulfonyl chloride (30 mg, 0.26 mmol) was then added via a syringe. The solution was stirred at room temperature for 4 hours. After standard workup with dichloromethane, the residue was purified by silica gel preparative TLC (2.0% methanol in dichloromethane) to afford 10a (39 mg, 91%): 1H NMR δ 7.43 (d, 4H, J=8.6 Hz), 7.20 (d, 2H, J=8.4 Hz), 6.98 (q, 2H), 6.89 (d, 2H, J=8.6 Hz), 4.41 (m, 2H), 4.16 (m, 2H), 3.87 (m, 4H), 3.27 (s, 3H), 3.05 (s, 3H), 1.46 (s, 9H).
