Procedure
Following a procedure similar to that described in Example 1(iii), but using α-(3,4-dimethylanilino)-α-(4-sulfamoylphenyl)acetonitrile [prepared as described in step (ii) above] and methacrolein as starting materials, the title compound was obtained as a slightly yellow powder (yield 43%), melting at 118-120° C.
