Reaction Steps
The procedure of Example 1 was repeated substituting 50 percent aqueous monomethylamine (174 ml.) for the ammonium hydroxide of Example 1. Sixty-four and seven-tenths grams of a white crystalline solid was obtained for a yield of 82.2 percent of theory based upon the 2,5-dihydrothiophene 1,1-dioxide. The solid sublimes over 180° C. and metls between 205° and 210° C.
