Pyridine → 1-[7-(2,3-Dihydro-indole-1-sulfonyl)-3,4-dihydro-1H-isoquinolin-2-yl]-ethanone

Participants

Reaction Steps

Pyridine (0.85 ml, 10.5 mmol) was added to a stirred solution of 2-acetyl-1,2,3,4-tetrahydroisoquinoline-7-sulfonyl chloride (0.96 g, 3.5 mmol) and 2,3-dihydro-1H-indole (0.42 g, 3.5 mmol) in 1,2-dichlorethane (40 ml) at room temperature. After 3 h, the solution was washed with water (40 ml), dried (MgSO4) and concentrated in vacuo to an oil. The oil was purified by column chromatography over silica gel eluting with a gradient of dichloromethane/methanol to afford the title compound (D5) as an oil (0.83 g, 67%), MS: m/z (MH+) 357.
