Reaction Steps

O-methyl(ethyl) O-aryl chlorothiophosphate, which was obtained by reacting O-methyl(ethyl) dichlorothiophosphate with phenol, was reacted with aminocarboxylic acid to give a hapten for immunoassay of phosphorothioate pesticides: to 46 mmol of O-methyl(ethyl) dichlorothiophosphate (10) dissolved in 30 mL of acetonitrile was added 45 g of ground K2CO3 and 42 mmol of phenol (11) dissolved in 30 mL of acetonitrile, and the mixture was stirred for 1 hour at room temperature. Then, the reaction mixture was filtered with cellite, the solvent was evaporated from the filtrate, and the remnant was subject to silica-gel column chromatography equilibrated with benzene/hexane (1:1, v/v) or hexane/ethylacetic acid (10:1, v/v), to obtain oily compound of O-methyl(ethyl) O-aryl chlorothiophosphate (12).
