Triethylamine → 4-[(Methylsulfonyl)amino]phenyl prop-2-enoate

Participants

Reaction Steps

A solution of 22.63 g (0.25 mol) of acryloyl chloride in 250 ml of methylene chloride was added over a period of 35 minutes to a mixture of 46.81 g (0.25 mol) of N-(4-hydroxyphenyl)methanesulfonamide, 25.30 g (0.25 mol) of triethylamine and 750 ml of methylene chloride at 0° C. The resultant solution was stirred at reduced temperature for 2.17 hours, washed three times with water and dried over magnesium sulfate. Concentration of the solution in vacuo gave a solid which after two recrystallizations from benzene and drying gave 13.4 g (22.2 percent yield) of N-(4-acryloyloxyphenyl)methanesulfonamide; m.p.=136.5° to 139.5° C.
