Participants

Reaction Conditions

Reaction Steps

A mixture of N-(4-hydroxypyridin-3-yl)-3-nitrobenzamide (1.33 g, 5.2 mmol) and P2S5 (2.40 g, 10.4 mmol) in pyridine (6.0 mL) and p-xylene (24 mL) was stirred at 140° C. for 18 h. The solvent was removed under vacuo while hot and the residue was purified by recrystallization from EtOH to afford 2-(3-nitrophenyl)thiazolo[4,5-c]pyridine as a yellow solid (1.08 g, yield: 81%). MS (ESI) calcd. for C12H7N3O2S (m/z): 257, found: 258 [M+1]+.
