실험 절차

(2S,4R)-(4-Amino-2-methyl-3,4-dihydro-2H-quinolin-1-yl)-(4-methoxyphenyl)-methanone (100 mg, 0.34 mmol), methyl-2-(4-bromophenoxy)-acetate (91 mg, 0.37 mmol), Pd2(dba)3 (17 mg, 0.02 mmol), 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl (8 mg, 0.00002 mol) and cesium carbonate (0.163 g, 0.0005 mol) were taken in a round bottom flask which was then flushed with nitrogen gas through a rubber septum. Toluene (2 mL) was injected into the flask through the rubber septum and the reaction mixture was stirred at 100° C. for 24 h. After cooling to room temperature the reaction mixture was filtered through Celite® and evaporated to give the crude product (0.236 g). This crude product was purified by silica gel chromatography eluting with 100% hexanes to 50/50 hexanes/ethyl acetate gradient give the title compound (37 mg, 24%).
