Procedure
Following a procedure similar to that described in Example 1(iii), but using α-(4-difluoromethoxyphenyl)-α-(4-methylsulfonylanilino)acetonitrile [prepared as described in step (ii) above] and crotonaldehyde as starting materials, the title compound was obtained as a white powder (yield 31%), melting at 98-99° C.
