Reaction Steps

Sodium methoxide (5.6 g) was added to a solution of methyl 4-chloro-2-fluoro-3-(methylsulphenyl)benzoate (85% pure, 19.2 g) in dry tetrahydrofuran and the mixture was stirred at room temperature overnight. Water was added and the mixture was extracted with ether, dried (MgSO4) and filtered. The filtrate was evaporated to dryness to give methyl 4-chloro-2-methoxy-3-(methylsulphenyl)benzoate (17.1 g) as a yellow oil NMR (CDCl3) 2.5(s,3H), 3.95(s,3H), 4.0(s,3H), 7.25(d,1H), 7.65(d, 1H) contaminated with 15% methyl 4-chloro-3-(chloromethylsulphenyl)-2-methoxybenzoate (determined by the ratio of NMR signals).
