Procedure
A mixture of trans-4-(3-methoxy-phenoxy)-cyclohexanecarboxylic acid methyl ester (0.20 g, 0.75 mmol) and hydrazine hydrate (0.035 ml, 0.73 mmol) 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 (0.18 g, 92%) as white solid, which was used in the next step without further purification.
