Reaction Steps

5.2.31 N-(3-chloro-4-oxonaphthalen-1(4H)-ylidene)biphenyl-4-sulfonamide (12b) was prepared according to the procedure for 12a except using 4-biphenylsulfonamide, which afforded the title compound 154 mg (37.8%) as a yellow solid. When TiCl4.2THF and THF were used instead, the reaction afforded the title compound 586.7 mg (71.9%) as a yellow solid, m.p.: 190-192° C.
