<p>Method for - (I) A = an aryl, heteroaryl or aliphatic residue linked with the SO2 via a C atom R = H, an aliphatic residue, or -CH2CHR'CONH2 R' = H or Me. Dyes, dyestuff intermediates, optical colour improvers, pharmaceuticals, insecticides, fungicides, textile glue monomers, etc. Acrylamide (14.5 g) was added to sulphanilamide (17.2 g) in DMF (20 ml) followed by 35% Me3N-(PhCH2)OH in MeOH (2 g), heated to 85-90 deg., cooled, dild. with PrOH (1 vol), stirred, filtered and dried, giving I (24 g), m.p. 168-168.5 deg.</p> |
