実験手順

A solution of 3-chloroperoxybenzoic acid (3.49 g) in dichloromethane (80 ml) was added to a stirred solution of 1-(4-fluoro-2-methylaminophenyl)-2(methylthio)ethanone (4.3 g), prepared in a similar manner to that described in Example 2, in dichloromethane (75 ml) under nitrogen over 15 minutes whilst maintaining the temperature below 25°. The mixture was stirred for a further 2 hours at ambient temperature. The solution was washed with saturated aqueous sodium hydrogen carbonate solution (3×50 ml) an evaporated in vacuo to give a solid product. Crystallisation from toluene gave 1-(4-fluoro-2-methylaminophenyl)-2-methylsulphinylethanone, m.p. 137°-138°.
