Reaction Steps

The title compound was prepared from 2-[3-({[(2R)-1-cyclopentylpyrrolidinyl]methyl}amino)-6-methyl-2-oxo-1(2H)-pyrazinyl]acetic acid hydrochloride (preparation 145) and 1H-indol-5-ylmethylamine (preparation 8), following the procedure described in preparation 45. The crude product was purified by chromatography using a Biotage™ (KP-Sil™ 60 Å silica gel) cartridge and dichloromethane:methanol:0.88 ammonia (95:5:0.5) as eluant. The product was further purified using preparative tic and dichloromethane:methanol:0.88 ammonia (90:10:1) as eluant to afford the title compound, (11 mg, 16%).
