実験手順
Compounds of Formula I, wherein D is CH, T is CH, M is C, Q is S, and q is 0, can be prepared according to the synthetic sequence shown in Scheme 7 and further detailed in the Examples section following. 4-(4-Nitrophenoxy)aniline (2), derived from (1) and 4-aminophenol, was cyclized with KSCN and Br2 in the presence of acid to provide thiazole (3). Subsequent reaction with ClCO2Me or butylisocyante (BuNCO) to give (4), followed by reduction with SnCl2 to give (5) and finally coupling with isocyanate afforded (6).
