Reaction Steps

Diazomethane (6 g., 0.143 mole) is generated via dropwise addition of a solution of Diazald® (43 g.) in ether (400 ml.) over 45 minutes to a warm (65%), stirred solution of potassium hydroxide (12 g., 0.214 mole) in carbitol-water (7:2, 90 ml.). The resulting yellow, ethereal diazomethane distillate is cooled to 0° and treated with a solution of ethyl 8-chlorocarbonyl-12-acetoxyheptadecanoate (8.1 g., 0.02 mole) (Example 7, Step D), in ether (40 ml.) added over a period of 15 minutes.
