Reaction Steps

A mixture of cis-4-(pyridin-2-yloxy)-cyclohexanecarboxylic acid methyl ester (0.39 g, 1.6 mmol) and hydrazine hydrate (0.40 ml, 8.2 mmol) in n-butanol (0.5 ml) was heated at 125° C. over night. After cooling to room temperature the reaction mixture was partitioned between dichloromethane (75 ml) and water (75 ml). The aqueous layer was washed with dichloromethane/75 ml). The combined organic layers were washed with water (75 ml) and brine (75 ml), dried over anhydrous sodium sulfate and concentrated in vacuo to give the crude title compound (0.35 g, 91%) as colorless oil, which was used in the next step without further purification. MS m/e: 236 (M+H+)
