実験手順

To a solution of 5-(4-methoxyphenyl)-1H-pyrazol-3-ylamine (12 g, 62.8 mmol) and N,N-diisopropylethylamine (10.96 mL, 62.8 mmol) in dry N,N-dimethylformamide (150 mL) at −10° C. was added a solution of 5-bromovaleryl chloride (8.4 mL, 62.8 mmol) in dry N,N-dimethylformamide (50 mL) slowly (˜40 min) and the reaction mixture was allowed to stir at −10 to 0° C. for 8 hrs. Sodium iodide (9.44 g, 62.8 mmol) was added at 0° C. and followed by N-acetylhomopiperazine (8.24 mL, 62.8 mmol) and N,N-diisopropylethylamine (10.96 mL, 62.8 mmol) and the reaction mixture was allowed to stir at 50° C. for 18 hrs. The solvent was removed in vacuo. The residue was dissolved in methylene chloride (500 mL) and saturated aqueous sodium bicarbonate (500 mL) and the mixture was stirred at room temperature for 30 minutes. The organic layer was separated, dried over sodium sulfate, and the solvent was removed in vacuo to provide 25.8 g (99%) of 5-(4-acetyl-1,4-diazepan-1-yl)-N-(5-(4-methoxyphenyl)-1H-pyrazol-3-yl)pentanamide as a thick light yellow oil (crude).
