Reaction Steps

To a solution of 0.300 g (0.965 mmol) of the product of Example 20 in 5.0 mL of DMF was added 0.419 g (3.038 mmol) of potassium carbonate followed by 0.166 g (1.013 mmol) of 3-picolyl chloride hydrochloride. The resulting mixture was stirred at room temperature for 15 h and then diluted with ether and water. The organics were washed with water, dried over Na2SO4, filtered and concentrated in vacuo to give a pale yellow solid. The solid was washed with ether/hexanes (1:1) and dried in vacuo to provide 0.334 g (86%) of the N-picolyl sulfonamide as a tan solid. Electrospray Mass Spec 402.9 (M+H)+
