Versuchsvorschrift

To a suspension of [2-chloromethyl-7-(3-trifluoromethyl-pyridin-2-yl)-quinazolin-4-yl]-(4-trifluoromethyl-phenyl)-amine hydrochloride (1.9 g, 0.0037 mol) in dry isopropanol (100 mL), add 20 equivalents of NaO-iPr (prepared from Na and isopropanol). Stir the pale yellow mixture at 60° C. for 5 hours, cool and evaporate the solvent under reduced pressure. Partition the residue between ethyl acetate and water and wash the organic layer with water (1×). Dry the organic layer (Na2SO4) and concentrate to give [2-isopropoxymethyl-7-(3-trifluoromethyl-pyridin-2-yl)-quinazolin-4-yl]-(4-trifluoromethyl-phenyl)-amine as a foam. IC50 in standard assay of capsaicin receptor activity is less than 10 nanomolar.
