Procedure

To a solution of the crude product from Step 2, in 5 ml of methylene chloride cooled to 0° C. was added triethylamine (42 mg, 0.41 mmol) and methanesulfonyl chloride (47 mg, 0.41 mmol). The reaction was slowly allowed to warm to room temperature and was stirred for 18 hr after which time it was diluted with 30 ml of methylene chloride, washed with 30 ml of 10% citric acid solution, dried filtered and concentrated to afford the product as an oil.
