Reaction Conditions

Reaction Steps

To a suspension of 2-(4-chlorobenzylthio)-5-nitrobenzo[d]oxazole (220 mg, 0.70 mmol) in ethanol/water (5 mL/5 mL) at 90° C. was added ammonium chloride (75 mg, 1.4 mmol), followed by iron powder (192 mg, 3.44 mmol). The resulting mixture was stirred for 4 h at 90° C. After cooling, ethyl acetate was added and the solution was passed through a pad of Celite®. The organic layer was then washed with brine, dried over anhydrous MgSO4 and evaporated to afford 190 mg (94%) of the title compound (LCMS RT=6.54 min, MH+ 290.9)
