Reaction Steps

10-Oxo-8-fluoro-dibenzo[b,f]thiepin-3-carboxylic acid (2 g; 6.94 mmoles) is partially dissolved in methanol (20 mL) and is treated with excess diazomethane in ether. The resulting solution is evaporated to dryness, triturated in methanol to yield 1.98 g (94%) of methyl 10-Oxo-8-fluoro-dibenzo [b,f]thiepin-3-carboxylate, m.p. 129°-131° C.
