Reaction Steps

Reaction of N-(2-chloro-4-fluoro-benzyl)-2-(2,2-dimethyl-5-oxo-[1,3]dioxolan-4-ylidene)-N-methoxy-acetamide (0.175 g, 0.51 mmol) with methanesulfonamide (0.073 g, 0.77 mmol) as described in the preparation of compound 22 gave 0.089 g (45% yield) of the title amide as a white solid after crystallization from ethyl acetate-hexane; mp=144° C. (decomposition). 1H NMR (400 MHz, CDCl3) δ: 3.36 (3H, s, SO2CH3), 3.71 (3H, s, OCH3), 4.96 (2H, s, NCH2), 6.60 (1H, s, CH), 6.95-7.32 (3H, m, aromatics), 8.96 (1H, broad s, NH). Anal. calcd for C13H14ClFN2O6S: C, 41.00; H, 3.70; N, 7.35; found: C, 41.03; H, 3.61; N, 7.29.
