Product 1

HCID 19070333HCID 19070333, compoundYield 50%

Procedure

As in Synthesis Example 1 but using 1.73 grams of 1,2-dicyano-4-nitrobenzene and 4.9 grams of 2-t-butylbenzenethiol, there was obtained 1.46 grams of 1,2-dicyano-3-(2-t-butylphenylthio)benzene (yield of 50%). Next, as in Synthesis Example 1 but using 1.46 grams of this benzene compound and 0.42 gram of BBr3 l there was obtained 0.73 gram of the end product (yield 45%, mp 160°-161° C.).
