실험 절차

A mixture of 2-(3-tert-butoxycarbonyl-propoxy)-4-chloro-5-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoic acid 2-trimethylsilanyl-ethyl ester (1.3 g, 2.2 mmol) and tetrabutyl-ammonium fluoride (6.6 mL, 6.6 mmol, 1 M in THF) in THF (20 mL) was stirred at rt for 30 minutes. The mixture was then concentrated and diluted with ether. The ether layer was washed with water, dried and concentrated to yield 2-(3-tert-butoxycarbonyl-propoxy)-4-chloro-5-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoic acid (0.8 g). MS [M+H]+: 485.1; tR=2.96 min (method 1)
