Dimethylamine → HCID 86615278, compound

Participants

Reaction Steps

Dimethylamine (1.05 ml, 2.1 mmol), acetic acid (0.81 ml), and formaldehyde (442 μl) were added to a solution of 1-allyl-7-(3,4-dihydro-1H-isoquinolin-2-yl)-2-methyl-1H-pyrrolo[2,3-c]pyridin-5-yl]-(4-methylpiperazin-1-yl)-methanone (600 mg, 1.40 mmol) prepared in Step 2 in ethanol (5 ml). The reaction mixture was refluxed overnight and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (methanol/dichloromethane=1/10, v/v). The resulting white solid (300 mg, 0.62 mmol) was dissolved in ethanol (2 ml) and then iodomethane (77.2 μl, 1.24 mmol) was added thereto. The reaction mixture was stirred overnight at room temperature and then filtered. The resulting residue was dried to give 100 mg of the titled compound as a white solid. The product was used in the subsequent step without further purification.
