1,2-Dimethoxyethane → 5-(4-Chlorophenyl)-N-methyl-8-nitro-1,2,3,4-tetrahydroisoquinoline

Participants

Reaction Steps

A mixture of 5-bromo-N-methyl-8-nitro-1,2,3,4-tetrahydroisoquinoline (4.07 g, 15 mmol), 4-chlorophenylboronic acid (3.5 g, 22.5 mmol), sodium carbonate (8.0 g, 75.5 mmol), 1,2-dimethoxyethane (60 ml), water (30 ml) and tetrakis(triphenyl-phosphine)palladium(0) (0.20 g, 0.17 mmol) was stirred at reflux for 3.5 h. Water (50 ml) was added and the mixture was extracted with ethyl acetate (100 ml). The crude mixture was recrystallized from ethanol (96%). Yield 3.62 g (80%). Mp 162-163° C.
