Procedimiento

A mixture of 2.0 g (0.0008 mol) of trans-ethyl 4-(4-aminocyclohexyl)benzoate, 1.25 ml of triethylamine and 1.26 ml (0.0084 mol) of benzyl chloroformate at 95% in 40 ml of dimethylformamide is stirred at room temperature for 3 hours. The mixture is poured into water, extracted with ethyl acetate and dried, and the solvent is evaporated off. The residue is purified by chromatography on a silica gel column, eluting with an 8/2 cyclohexane/ethyl acetate mixture. The compound of the title is obtained.
