Procedure

A solution of N-(2,2-Diphenylethyl)-N-(2-chloro-3-trifluoromethylbenzyl)-3-hydroxypropylamine (186 mg, 0.42 mmole) and methyl 3-hydroxybenzoate (63 mg, 0.42 mmole) in 15 mL of THF was treated with Ph3P (110 mg, 0.42 mmole) and diisopropylazodicarboxylate (93 mg, 0.46 mmole). The reaction was stirred for 18 hours, diluted with H2O, and extracted with Et2O. The extracts were washed with H2O, dried, and the solvent evaporated. The residue was chromatographed on a silica gel column, and elution with 10% EtOAc in hexane gave the titled product, 64 mg (26% yield). MS (ESI) 583 (MH+).
