Reaction Steps

3,6-dimethyl-4-[(4-nitrophenyl)oxy]-1,2-benzisoxazole (Intermediate 20, 208 mg) was dissolved in ethanol (10.0 ml) and tin chloride dihydrate (991 mg, 4.39 mmol) was added. The reaction mixture was stirred and heated at reflux for 4 hours. After the removal of the volatiles, water was added and the reaction mixture was extracted two times with ethyl acetate. The collected organic were dried over sodium sulphate, filtered and evaporated to afford 260 mg of the title compound.
