Reaction Steps

3-(4-Nitrophenyl)isoxazole (Intermediate 4, 8 g, 42 mmol) was added to acetic acid (126 ml) and then SnCl2 (39 g, 205 mmol) in HCl (42 ml) was added. The reaction was allowed to stir for 4 hours and then 1M NaOH was added to bring the solution to pH˜11. The water layer was extracted with EtOAc and then the organic layers were collected, dried over Na2SO4, and dried under vacuum to yield the product (4 g).
