Reaction Steps

Methyl mercaptan (excess) is passed into a rapidly stirred solution of sodium methoxide (13.5 g., 0.25 mole) in dry methanol (200 ml.) at 0° C. to generate sodium methylmercaptide. The resulting solution is treated with dimethyl 2-bromoazelate (55.0 g., 0.186 mole), then stirred and heated at reflux under nitrogen for 5 hours. The reaction solution is concentrated in vacuo, diluted with ether and filtered. The filtrate is washed with water (until the washings are neutral), dried over sodium sulfate and distilled providing the title compound as a colorless liquid (28.4 g., 58%), bp 0.2 mm 128°-138° C.; pmr (CLCl3) δ 2.10 (s, 3H), 2.31 (t,2H), 3.20 (t,H), 3.63 (s, 3H) and 3.71 (s, 3H).
