To 5-nitro-2-p-tolylbenzo[d]oxazole (4.8 g, 18.90 mmol) in ethyl acetate/acetic acid (250 mL/1 mL) was added palladium on carbon (480 mg). The reaction vessel was purged three times with nitrogen, followed by hydrogen three times, and then left stirring under hydrogen for 16 h. The reaction vessel was finally purged three times with nitrogen, before filtration on a pad of Celite®, which was washed with ethyl acetate. The organic solution was washed with saturated aqueous Na2CO3, followed by brine. The combined organic layers were dried over anhydrous MgSO4 and evaporated to afford 2.5 g (60%) of the title compound.
