Participants

Reaction Steps

A solution of 2 g (5 mmol) of (±)-6-fluoro-N,N,9-trimethyl-1-oxo-2-(phenylmethyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-4-carboxamide and of 1.6 g (7 mmol) of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone in 250 ml of dichloromethane is stirred for 1 h. The organic phase is washed and dried over sodium sulphate. The solvent is evaporated under reduced pressure and the residue is purified by chromatography on a column of silica gel, elution being carried out with a mixture of dichloromethane and ethyl acetate. The product is crystallized from diethyl ether. 1 g (2.6 mmol) of product is obtained.
