Procedure

To a slurry of the product from Method K (4.1 g/0.018 mol) in DMF (15 mL) and cooled to 0° C. was added 1.0 g (0.025 mol) of 60% sodium hydride in mineral oil and the resulting mixture stirred at 0° C. for 15 minutes. Benzenesulfonyl chloride (3.2 g/0.018 mol) was added, the reaction mixture warmed to room temperature and stirred for 2 hours. Water was then added (15 mL) and the resulting solid removed by filtration and dried in vacuo affording 5.9 grams (89%) of the title compound.
