To a solution of 6-hydroxymethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (85 mg, 0.323 mmol) in CH2Cl2 (1.5 mL) is added a solution of 4-chloro-3-trifluoromethyl-phenol (76 mg, 1.23 eq.) in CH2Cl2 (0.5 mL), PPh3 (127 mg, 1.5 eq.), and 1,1′-(azodicarbonyl)-dipiperidine (122 mg, 1.5 eq.). The mixture is stirred at room temperature overnight. All the solvent is removed under reduced pressure and the mixture is purified by column chromatography (silica gel, EtOAc/Hexane, gradient) to give 70 mg of 6-(4-chloro-3-trifluoromethyl-phenoxymethyl)-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester
