Reaction Steps

N-(4-Hydroxy-pyridin-3-yl)-2-nitro-benzamide was prepared using a procedure similar to that described above using 4-hydroxy-3-aminopyridine and 2-nitrobenzoyl chloride. A mixture of -(4-Hydroxy-pyridin-3-yl)-2-nitro-benzamide (2.6 g, 0.01 mol) and P2S5 (4.44 g, 0.02 mol) in pyridine (12.5 mL) and p-xylene (50 mL) was stirred at 140° C. for 18 hrs. The solvent was removed under vacuo and the residue was purified by recrystallization to give 2-(2-nitrophenyl)thiazolo[4,5-c]pyridine as a yellow solid (1.43 g, yield: 55%).
