Triethylamine → 3-[2-Benzyl-1-oxo-1,2-dihydroisoquinolin-6-yl]-acrolein

참여 물질

반응 단계

A mixture of 2-benzyl-6-bromo-1,2-dihydro-1-oxoisoquinoline (1 g, 3.2 mmol), acrolein dimethyl acetal (2.6 mL, 22.4 mmol), Pd(OAc)2 (15 mg, 0.064 mmol), P(o-tolyl)3 (78 mg, 0.26 mmol) and Et3N (0.5 mL, 3.84 mmol) in DMF (2 mL) is heated in a sealed tube apparatus at 120° for 48 hours. After cooling to room temperature, the reaction mixture is diluted with EtOAc, filtered, washed with saturated NaCl solution, dried over MgSO4 concentrated in vacuo, and the residue is chromatographed (silica gel 1:4 EtOAc/hexane) to yield 3-[2-benzyl-1-oxo-1,2-dihydroisoquinolin-6-yl]-acrolein.
