実験手順: To a solution of 5-chloromethyl-2-methoxy-benzonitrile (246 mg, 1.354 mmol, example 29) in tetrahydrofuran (10 mL) at room temperature was added morpholine (1.193 mL, 13.54 mmol). The reaction mixture was heated at reflux for 4 h. The reaction was concentrated in vacuo (with heating) to remove morpholine and tetrahydrofuran to afford 2-methoxy-5-morpholin-4-ylmethyl-benzonitrile as a yellow oil (311.2 mg, 99%). The crude product was used without further purification. The reaction mixture was heated at reflux for 4 h The reaction was concentrated in vacuo (with heating) to remove morpholine and tetrahydrofuran

実験手順: To a solution of 5-chloromethyl-2-methoxy-benzonitrile (254 mg, 1.399 mmol) in ethanol (10 mL) was added potassium carbonate (387 mg, 2.798 mmol). The mixture was heated at reflux for 12 h. Upon cooling to room temperature, the solvent was removed. Water (2-5 mL) was added and the product was extracted with diethyl ether (2×20 mL). The organic layers were washed with brine (1×5 mL) and dried over anhydrous sodium sulfate. The solid was then filtered off, and the filtrate was concentrated in vacuo. Purification of the crude residue by flash chromatography (Biotage system, KP-Sil™ 32-63 μm, 60 Å silica gel) eluting with 20% ethyl acetate in hexanes yielded 5-ethoxymethyl-2-methoxy-benzonitrile (182 mg, 68%).
