Benzylamine → Benzyl[2-(diethylamino)ethyl]amine

2-(diethylamino)-ethyl chloride hydrochloride (1 g, 5.81 mmol) and benzylamine (1.3 ml, 11.62 mmol) were dissolved in t-butanol (40 ml), triethylamine (3.2 ml, 23.24 mmol) was added thereto, and the resulting solution was refluxed for 12 hours. The solution was cooled to room temperature, and distilled under a reduced pressure to remove the solvent. The resulting solid was removed by filtration under a reduced pressure, and the residual solution was extracted with ethylacetate The separated organic layer was washed with saturated sodium bicarbonate aqueous solution, dried over magnesium sulfate, filtered and distilled under a reduced pressure to obtain the title compound 560 mg (yield: 47%).
