Reaction Steps

To a solution of 2-{2-[(4-nitrophenyl)amino]-3H-imidazo[4,5-b]pyridin-3-yl}ethanol (2.2 g) and triethylamine (10 mL) in THF (100 mL) was added methanesulfonyl chlorode (1.1 mL) at 0° C., and the mixture was stirred at 0° C. for 2 h. The mixture was poured into water and extracted with AcOEt. The organic layer was washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure. A mixture of the residue and potassium carbonate (3.1 g) in NMP (30 mL) was stirred at 100° C. overnight. After cooling to room temperature, the mixture was diluted with water. The formed crystals were collected by filtration to give the title compound (1.7 g).
