Triethylamine → (S)-N-(3-bromophenyl)-2-methyl-4-(5-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-N'-(methylsulfonyl)piperazine-1-carboximidamide

Participants

Reaction Steps

The carbamimidate from step B (100 mg, 0.27 mmol), (S)-5-methyl-4-(3-methylpiperazin-1-yl)-7H-pyrrolo[2,3-d]pyrimidine, from Example 1, step B (63 mg, 0.27 mmol), and triethylamine (77 μl, 0.27 mmol) were combined in MeCN (1.5 ml) and heated to reflux for 2 hours. The mixture was concentrated and purified by preparative HPLC to afford (S)—N-(3-bromophenyl)-2-methyl-4-(5-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-N′-(methylsulfonyl)piperazine-1-carboximidamide.
