Reaction Steps

(4-Amino-3-methyl-cyclohexylmethyl)-phenyl-amine (113 mg, 0.52 mmol) in dry THF (5 mL) and TEA (105 mg, 1.04 mmol) is treated with 2-chloro-5-(trifluoromethyl)benzoyl chloride (139 mg, 0.57 mmol). After stirring at RT for 2 hours, the solvent is removed in vacuo and the residue is partitioned between water and DCM. The mixture is passed through a phase separator and the organic portion is concentrated in vacuo. Purification of the crude residue by chromatography on silica eluting with iso-hexane:EtOAc (9:1 increasing to 2:1) affords the title compound. 1H NMR (400 MHz, DMSO-d6) δ 8.47 (1H, d), 7.82 (1H, d), 7.73 (2H, m), 7.07 (2H, t), 6.56 (2H, d), 6.49 (1H, t), 5.55 (1H, m), 3.93 (1H, m), 2.86 (2H, m), 2.23 (1H, m), 1.88 (1H, m), 1.78 (1H, m), 1.70 (1H, m), 1.59 (2H, m), 1.31 (1H, m), 1.11 (1H, m), 0.92 (3H, d).
