Reaction Steps

A solution of EXAMPLE 157E (0.051 g), methanesulfonamide (0.015 g), 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide hydrochloride.HCl (0.037 g) and 4-dimethylaminopyridine (0.019 g) were stirred together in dichloromethane (1 mL) at room temperature overnight. The reaction mixture was loaded onto silica gel and eluted using a gradient of 0.5% to 3.25% methanol/dichloromethane to provide the title compound. 1H NMR (300 MHz, dimethylsulfoxide-d6) δ ppm 12.84 (s, 1H), 11.81 (s, 1H), 8.03 (d, 1H), 7.79 (d, 1H), 7.62 (d, 1H), 7.56-7.41 (m, 3H), 7.41-7.32 (m, 2H), 7.29 (s, 1H), 7.00 (d, 1H), 4.96 (s, 2H), 4.00 (d, 2H), 3.93 (t, 2H), 3.16 (s, 3H), 3.11 (s, 3H), 3.03 (t, 2H), 2.13 (s, 3H), 1.71 (d, 1H), 1.58-1.00 (m, 7H), 0.96 (s, 3H), 0.84 (s, 3H).
