反応手順

A solution of oxone (18.42 g, 0.03 mol) in water (70 ml) was added dropwise to the vigorous stirred solution of 4-methylthiobenzonitrile (1.49 g, 0.01 mol) in methanol (50 ml) at 20° C. and stirring was continued for three hours. The reaction mixture was diluted with water (50 ml) and extracted with ethyl acetate. The ethyl acetate extract was washed with water, dried over anhydrous sodium sulphate and concentrated under reduced pressure to finish the title compound (1.3 g, 72.2%), mp 145-149° C. The compound was used with out any purification for the next step. 1H-NMR (CDCl3):δ 3.1 (s, 3H), 7.8-7.9 (d, 2H), 8.08-8.1 (d, 2H).
