Procedure
A mixture of trans-4-o-tolyloxy-cyclohexanecarboxylic acid methyl ester (0.091 g, 0.36 mmol) and hydrazine hydrate (0.02 ml, 0.36 mmol) was heated at 120° C. for 22 h. After cooling to room temperature the reaction mixture was suspended in toluene. After evaporation of the solvent the residue was dried in high vacuo (1-2 mbar) to give the crude title compound (0.73 g, 81%) as white solid, which was used in the next step without further purification.
