실험 절차

A mixture of 2-(3-bromo-4-methoxyphenyl)ethanamine (1 g; 4.35 mmol), 2-chloro-5-ethyl-pyrimidine (0.56 g; 3.92 mmol) and DIEA (0.84 g; 6.53 mmol) in n-butanol was heated to reflux for 14 hr. Upon cooling, the reaction mixture was concentrated and partitioned between 1N HCl and ether. The aqueous phase was basified with 6N NaOH and extracted with ether. The combined organic phases were washed with a saturated solution of NaHCO3, dried over MgSO4, filtered and concentrated to provide a colorless solid, which was triturated with hexane, filtered and dried to provide the title compound as a white crystalline solid (0.89 g; 67% yield).
