Hydrochloric Acid → N-(1H-Indol-5-ylmethyl)-2-[3-({[(2R)-1-isobutylpyrrolidinyl]methyl}amino)-6-methyl-2-oxo-1(2H)-pyrazinyl]acetamide

참여 물질

반응 단계

HOBT (24 mg, 0.18 mmol), WSCDl.HCl (29 mg, 0.15 mmol), N-methylmorpholine (39 ml, 0.36 mmol) and 1H-indol-5-ylmethylamine (preparation 8) (19 mg, 0.13 mmol) were added to a solution of 2-[3-({[(2R)-1-isobutylpyrrolidinyl]methyl}amino)-6-methyl-2-oxo-1(2H)-pyrazinyl]acetic acid (preparation 62) (38 mg, 0.12 mmol) in N,N-dimethylformamide (2 ml), and the reaction was stirred at room temperature overnight. The mixture was evaporated under reduced pressure and the residue purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (95:5:0.5) as eluant. The product was repurified using a Biotage™ (KP-Sil™ 60 Å silica gel) cartridge and dichloromethane:methanol:0.88 ammonia (95:5:0.5) as eluant to afford the title compound, (16 mg, 30%).
