Procedure

35.0 g of the product of Step A, 350 ml of acetone, 44.6 g of potassium carbonate and 40.7 g of dimethyl sulfate (neutralized on potassium bicarbonte) and was allowed to return to ambient temperature. Water was added and extraction was carried out with ether. The extracts were washed, dried and concentrated to dryness under reduced pressure to obtain 39.8 g of the desired product.
