Yield:927823-01-6 31%

Reaction Conditions:

with triethylamine in dichloromethane;Reflux;Inert atmosphere;

Steps:

4.1.5.10. 3,4-Dimethoxy-N-[(2,2-dimethyl-2H-chromen-6-yl)methyl]-N-phenylbenzenesulfonamide (6e)

General procedure: A mixture of 22 mg (0.093 mmole) of 4a, 0.1 mL (164 mg,0.93 mmole, 10 equiv) of benzenesulfonyl chloride, and 1 mL of triethylaminein 2 mL of methylene chloride was refluxed overnight.After cooling, the reaction mixture was concentrated in vacuo, andpurified by column chromatography using ethyl acetate/hexane(1:6) as an eluent to afford 9 mg (0.024 mmole) of N-[(2,2-dimethyl-2H-chromen-6-yl)methyl]-N-(propan-2-yl)benzenesulfonamide(5a, 26%). All 15 sulfonamides were synthesized by the samemethod.
