Procedure

A solution of Example 173A (54.1 mg, 0.1 mmol) in pyridine (2 mL) and triethylamine (1 mL) at room temperature was treated with 2-methoxyethyl chloroformate (0.2 mmol), stirred for 18 hours, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 0-5% methanol/dichloromethane) to provide the desired product. MS (ESI(−)) m/e 642 (M−H)−; 1H NMR (300 MHz, DMSO-d6) δ8.66 (t, 1H), 8.55 (d, 1H), 7.89 (dd, 1H), 7.75 (d, 2H), 7.30-7.40 (m, 2H), 7.31-7.25 (m, 2H), 7.21-7.07 (m, 2H), 6.90 (d, 2H), 4.16-4.12 (m, 2H), 3.63 (q, 2H), 3.54-3.43 (m, 4H), 3.31-3.20 (m, 8H), 3.23 (s, 3H).
