Versuchsvorschrift

2,3-dimethylphenyl 4-nitrophenyl ether (Intermediate 73, 865 mg) was dissolved in ethanol (10 mL) to give a pale yellow solution. Hydrazine hydrate 50% (0.698 mL, 7.1 mmol) and Pd/C (37.8 mg, 0.36 mmol) were added. The reaction mixture was stirred at 90° C. for 1 hour. The reaction mixture was filtered and the organic phase was evaporated under vacuum to afford the title compound as a pale yellow oil (796 mg).
