Reaction Conditions

Reaction Steps

A mixture of trans-4-(pyridin-3-yloxy)-cyclohexanecarboxylic acid methyl ester (0.141 g, 0.599 mmol) and hydrazine hydrate (0.029 ml, 0.59 mmol) in n-butanol (0.5 ml) was heated at 120° C. for 22 h. After cooling to room temperature the reaction mixture was partitioned between ethyl acetate (50 ml) and 1 M aqueous sodium hydroxide solution (50 ml). The organic layer was separated, dried over anhydrous sodium sulfate and concentrated in vacuo to give the crude title compound (0.061 g, 43%) as white solid, which was used in the next step without further purification. MS m/e: 236 (M+H+)
