Participants

Reaction Steps

In an analogous manner to that described in Example 1(B). 36.5 g (131.9 mmol) of methyl 3-[(3-chlorobenzyl)oxy]benzoate were heated at reflux for 16 hours with 26.7 g (66 mmol) of Lawesson reagent in xylene and thereafter chromatographed on silica gel. Elution with hexane/toluene (2%, 5% and 10%) yielded 28.2 g (73%) of O-methyl 3-[(3-chlorobenzyl)oxy]thiobenzoate as an orange, crystallizing oil.
