Reaction Steps

To a suspension of NaH (60% dispersion in mineral oil, 3.97 g, 99.3 mmol) in DME (75 mL) was added an ice-cold solution of N-[2-(chloroacetyl)-5-methoxyphenyl]acetamide (12.00 g, 49.7 mmol) (Example 11) in DME (165 mL) at 0° C. The mixture was stirred under argon for 15 minutes, then 2 N HCl (75 mL) solution was added slowly. The mixture was extracted with dichloromethane. The combined organic layers were dried over MgSO4 and concentrated to yield a solid. The crude material was purified on silica gel eluting with EtOAc/hexane (1:1) and then EtOAc to give a reddish solid (7.87 g, 77%) with minor impurities: LC/MS m/z 206 (M+H)+; 1H NMR (400 MHz, DMSO-d6) δ 7.94 (d, 1H), 7.59 (d, 1H), 6.80 (dd, 1H), 4.51 (s, 2H), 3.85 (s, 3H), 2.24 (s, 3H).
