Procedure

In an analogous manner to that described in Example 1(B), 40 g(0.165 mol) of methyl 3-(benzyloxy)benzoate were heated at reflux for 8 hours with 33.4 g (0.0826 mol) of Lawesson reagent in xylene and thereafter chromatographed on silica gel, whereby there were obtained 21.7 g (51%) of O-methyl 3-(benzyloxy)thiobenzoate as a red-brown oil which gradually crystallized upon standing.
