Versuchsvorschrift
NaH (60% in mineral oil) (1.86 mmol) is added to a solution a 1,3,4,5-tetrahydro-benzo[b]azepin-2-one (1.55 mmol) in 5 mL of DMF at 0° C., After stirring at 0° C. for 15 minutes, the mixture is allowed to warm up to room temperature. p-Methoxybenzyl chloride (1.94 mmol) is added to the mixture. After stirring at room temperature for 16 hours, the mixture is poured into 50 mL of water and extracted with EtOAc (3×25 mL). The organic layer are combined, washed with brine and dried over MgSO4. After removing the solvent under reduced pressure, the residue is purified by flash column chromatography (silica gel) to provide the desired product 1-(4-ethoxy-benzyl)-1,3,4,5-tetrahydro-benzo[b]azepin-2-one as white solid. Yield: 90%. MS: (ES+): 282.1 [M+1].
