Procedure
To a solution of 2-amino-4-(3-trifluoromethyl-pyridin-2-yl)-benzamide (3.56 mmol) and pyridine (3.91 mmol) in THF (20 ml), add 4-methoxy-butyryl chloride (3.91 mmol). Stir the mixture 20 minutes at room temperature, add 20 ml of 20% NaOH, stir for 60 minutes at 50° C. Concentrate, add water, filter, acidify to pH=6, collect the precipitate to obtain 2-(3-benzyloxy-propyl)7-(3-trifluoromethyl-pyridin-2-yl)-quinazolin-4-ol.
