Reaction Steps
3.1 A solution of 0.72 g of 3,4-diamino-2-chloropyridine, 0.9 g of 4-nitrophenyl isothiocyanate and 0.78 ml of N,N-diisopropylcarbodiimide in 30 ml of DMF is stirred at room temperature for 16 hours, then at 500 for 6 hours. The solvent is separated off, and the residue is crystallised from methanol, giving 1.2 g of 4-chloro-2-(4-nitrophenylamino)-3H-imidazo-[4,5-c]pyridine (“6”).
