Gompper, Rudolf published the artcile2,4-Bis(dialkylamino)-5-ethylidene-4,5-dihydro-1,3-thiazole and 2,4-bis(dimethylamino)-5-vinyl-1,3-thiazole, SDS of cas: 14294-10-1, the publication is Synthesis (1981), 647-8, database is CAplus.
Reaction of Me2NCR:NCSR1 (I; R = R1 = Me2N; R = H, R1 = morpholino) with BrCH2CH:CH2 gave an azavinaminidinium salt which upon treatment with NaNH2/NH3 or KOCMe3 gave the ethylidenethiazolines II, which upon heating or treatment with 4-MeC6H4SO3H rearranged to III. Reaction of the azavinamidinium salt from I (R = R1 = NMe2) with NaH in THF gave IV (R2 = H), which upon reaction with HBF4 gave II.HBF4 (R = H, R1 = NMe2) and with PhNCS gave IV (R2 = PhNHCS).
