Procedure

A room temperature solution of Example 43B (30 mg, 0.051 mmol), methyl chloroformate (0.05 mL, 0.65 mmol), N,N-diisopropylethylamine (0.1 mL, 0.57 mmol) and DMAP (3 mg, 0.02 mmol) in dichloromethane (1 mL) was stirred for 16 hours, treated with 4M HCl (0.3 mL), and concentrated. The concentrate was purified by flash column chromatography on silica gel with 50-100% ethyl acetate/hexanes to provide the desired product. MS (ESI(−)) m/e 635 (M−H)−; 1H NMR (400 MHz, DMSO-d6) δ 8.89 (br s, 1H), 8.65 (d, 1H), 8.56 (t, 1H), 7.92 (, 3H), 7.43 (d, 2H), 7.35 (m, 3H), 7.12 (dt, 1H), 3.50 (s, 3H), 3.18 (d, 2H), 1.98 (m, 3H), 1.72-1.55 (m, 12H).
