Dimethylamine → HCID 10225808, compound

Participants

Reaction Steps

A mixture of 220 mg (0.5 mmol) crude (4-benzyloxy-phenyl)-[6-(4-chloromethyl-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl]-amine in 15 ml absolute ethanol is treated with 0.8 ml (5 mmol) of a 33% solution of dimethylamine in ethanol (Fluka, Buchs, Switzerland) and then heated under reflux for 1 h. The resulting solution is cooled and the solvent evaporated. The residue is dissolved in a mixture of dichloromethane and ethanol (95:5), washed with water, dried over sodium sulfate and the solvent evaporated. The solid material is then suspended in ether stirred for 5 min and filtered. Purification of the crude material through flash chromatography using dichloromethane/ethanol 9:1 plus 1% conc. ammonia gives the title compound; m.p. 272-274° C.; MS-ES+: (M+H)+=450.
