Reaction Steps

EDIC hydrochloride (0.33 mmol, 0.07 g) was added in one portion to a suspension of (4-amino-benzyl)-methyl-(tetrahydro-pyran-4-yl)-amine Compound 1d (0.25 mmol, 0.06 g), 4-chloro-3-trifluoromethyl-benzoic acid Compound 7a (0.22 mmol, 0.05 g) and HOBt (0.22 mmol 0.03 g) in DMF (5.0 mL) at 0° C. The resulting suspension was warmed to r.t. and a crystal of DMAP and Et3N (0.65 mmol, 0.1 mL) were added. The mixture was stirred overnight and produced an orange-yellow suspension. The suspension was poured into water and the aqueous layer was extracted with EtOAc (25 mL). The organic layer was washed with water (2×20 mL), then a solution of 5% NaOH (10 mL) and brine. The organic layer was separated, dried over Na2SO4 and filtered. The solvent was removed in vacuo to yield a residue, which was purified via preparative TLC (15:1 CH2Cl2:MeOH) to provide 4-chloro-N-(4-{[methyl-(tetrahydro-pyran-4-yl)-amino]-methyl}-phenyl)-3-trifluoromethyl-benzamide Compound 7b (0.06 g, 63%) as a pale yellow solid. MS m/e 427 (M+H, 100%).
