Triethylamine → [4-(4-chlorophenyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-piperidin-4-ylmethyl]-methylamine

Participants

Reaction Steps

A solution of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (15.5 mg, 0.1 mmol), [4-(4-chlorophenyl)-piperidin-4-ylmethyl]-methylamine bis-hydrochloride (34 mg, 0.11 mmol) and triethylamine (150 μL, 0.7 mmol) in n-butanol (1 ml) was heated at 100° C. in a microwave reactor for 60 minutes. After cooling the reaction the solvents were concentrated. Purification on SCX-II acid resin, eluting with methanol then 2M ammonia/methanol, followed by further purification by flash column chromatography on silica, eluting with 15% methanol in dichloromethane, gave [4-(4-chlorophenyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-piperidin-4-ylmethyl]-methylamine (12.3 mg, 0.034 mmol, 34%). LC-MS (LCT2) m/z 356 [M+H+], Rt 2.64 min.
