mixture of the nitrile derivatives (3e6) (1 eq.), 2-
cyanoguanidine (3 eq. per site) and KOH (1 eq. per site) in DMSO
(C: 0.1 M) was stirred at 80 ꢀC for 16h. Distilled water was added
and the crude was recrystallized at 80 ꢀC during 15 min. The
precipitated solid was then hot filtrated on Celite, washed with
acetonitrile and purified by recrystallizations in THF. Yields: 3(a)
98%, yellow solid; (4a) 74%, orange solid; (5a) 91%, dark red solid;
(6a) 77%, green solid. All amounts are calculated based on each
reactive site (-CN) of the starting precursor.
