Benzo-1,3-dioxole-5-methylamine → HCID 19007128, compound

Participants

Reaction Steps

3.32 g of N-(2-paratoluenesulfonyloxyethyl)-8-chloro-5-quinolinesulfonamide was reacted with 30 ml of a tetrahydrofuran solution containing 3.41 g of 3,4-methylenedioxybenzylamine in a sealed vessel at 70° C. for 17 hours, and the solvent was removed by distillation under reduced pressure to obtain a residue. The thus obtained residue was subjected to purification by means of a column for chromatography packed with 200 g of silica gel (Wacogel C-200, manufactured by Wako Pure Chemical Industries, Ltd., Japan) using, as an eluent, a mixture of methanol and chloroform (5% methanol) to thereby obtain 1.80 g of N-[2-(3,4-methylenedioxybenzylamino)ethyl]-8-chloro-5-quinolinesulfonamide (13) (yield: 57%)
