To a solution of cis-(4-Amino-cyclohexyl)-methanol (Tetrahedron Lett., 1970, 11, 4285-4288) (0.75 g, 5.80 mmol) in THF (10 ml) is added water (1.8 mL), triethylamine (2.023 mL, 14.51 mmol) and 2-chloro-5-(trifluoromethyl)benzoyl chloride (1.411 g, 5.80 mmol). The RM is stirred at RT for 1 hour. The reaction mixture is partitioned between EtOAc and water. The organic phase is washed successively with water, saturated sodium bicarbarbonate and saturated brine, dried over MgSO4, filtered and the solvent removed in vacuo. Purification by chromatography on a pre-packed silica gel column using 0-100% EtOAc in isohexane gradient elution gave the desired product as a colourless solid.
