Procedure

A solution of N-(2,2-diphenylethyl)-N-(2-chloro-3-trifluoromethylbenzyl)-3-hydroxypropylamine (186 mg, 0.42 mmol) and methyl 3-hydroxybenzoate (63 mg, 0.42 mmol) in 15 mL of THF was treated with Ph3P (110 mg, 0.42 mmol) and diisopropylazodicarboxylate (93 mg, 0.46 mmol). The reaction was stirred for 18 h, diluted with H2O, and extracted with Et2O. The extracts were washed with H2O, dried, and the solvent evaporated. The residue was purified via silica gel column chromatography eluted with 10% EtOAc:hexane to yield the titled product, (64 mg, 26%). MS (ESI) 583 (M+H+).
