Reaction Steps

A solution of 15.0 g of (2-chloro-4-fluoro-5-nitrophenyl)-ethyl carbonate in 100 ml of dimethyl formamide was treated with 18.6 g of cesium carbonate, 7.1 ml of iodomethane and 7 ml of methanol and stirred overnight at room temperature. The reaction mixture was poured into water and extracted twice with ether. The extracts were washed twice with water and then with brine, dried over magnesium sulfate and concentrated to afford 11.4 g of the subtitle compound. mp. 69-70° C. Ex. 57, C.
