Participants

Reaction Steps

The title compound was prepared by a similar method to preparation 49 from 2-[3-({[(2R)-1-isobutylpyrrolidinyl]methyl}amino)-6-methyl-2-oxo-1(2H)-pyrazinyl]acetic acid hydrochloride [see preparation 62] and (3-methyl-1H-indol-5-yl)methylamine (72 mg, 0.45 mmol) [see preparation 36]. The crude product was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (92:7:1) as the eluant, to afford the product as a foam. This was dissolved in methanol (5 ml) and hydrochloric acid (1M, 0.58 ml, 0.58 mmol), to afford the product, (56%).
