Reaction Steps

To a solution of (RS)-1-(tert-butyloxycarbonyl)-2-((5-(4-fluorophenyl)-furan-2-yl)carbonyl)piperidine (2.0 g, 5.36 mmol) in diethylene glycol (20 g), was added hydrazine hydrate (0.31 ml, 5.36 mmol) and the resultant mixture heated at 100° C. for 30 min. After cooling to room temperature, potassium hydroxide (1.0 g, 17.8 mmol) was added and the mixture heated at 200° C. for 18 h. The reaction mixture was then poured into water (100 ml) and extracted with diethyl ether (3×75 ml). The combined organic extracts were dried (Na2SO4) and evaporated in vacuo to give the title compound as a brown oil (0.88 g, 63%).
