Procedure

Intermediate 66B (306 mg, 1.23 mmol) was dissolved in dichloromethane (5 mL) and was treated with 2M hydrochloric acid solution in diethyl ether (6.18 mL, 12.4 mmol). The resulting mixture was stirred for 2 hour then was concentrated under reduced pressure. The oily residue was dried overnight in a 40° C. vacuum oven to provide intermediate 66C as an off-white solid in quantitative yield. 1H-NMR (400 MHz, (CD3)2SO) δ: 1.38 (d, 3H), 1.43 (d, 3H), 2.67 (d, 3H), 3.97 (d, 1H), 8.51 (broad s, 3H), 8.76 (q, 1H).
