Did you check the literature? Done some research first? Also what is the red box supposed to indicate?

I have searched for a method and here is an idea which i wanted to discuss with u
The idea is dependent on N,N-Dimethylacetamide dimethyl acetal
I have abstract for this paper (if somone have access to the paper ,plz upload it)
Cationic 1,3-diazadienes in annulation reactions. Synthesis of pyrimidine, thiadiazine dioxide and triazine derivatives.
Landreau, Cyrille; Deniaud, David; Reliquet, Alain; Reliquet, Francoise; Meslin, Jean Claude. Laboratoire de Synthese
Organique, UMR CNRS 6513, Faculte des Sciences et des Techniques, Nantes, Fr. Journal of Heterocyclic Chemistry (2001),
38(1), 93-98. Publisher: HeteroCorporation, CODEN: JHTCAD ISSN: 0022-152X. Journal written in English. CAN 135:33464
AN 2001:223206
Triazapentadienium iodides Me2NCR1:NC(SMe):NH.HI [R1 = H, Me], prepd. from Me2NCR1:NCSNH2, are efficient intermediates
in heterocyclic synthesis. They react with ketenes, sulfenes, Ph isocyanate or isothiocyanate and di-Me acetylenedicarboxylate
affording dihydropyrimidinones, thiadiazine dioxides, triazinones, triazinethiones, and pyrimidines.
It is easy to substitute the SMe in the final compound .....??Isn't it????

That is very possible. Scifinder is only a reference database, you don't get any journal subscriptions with it. Let's get back on topic now.

nobody answered me .....
Can I easily convert SMe into CH2COOH ??? (I think it can be easily done via dimethylmalonate and sodium ethoxide followed by decarboxylation)
