반응 단계
For compound (A48) (S)-2-((S)-2-Amino-3,3-dimethyl-butyrylamino)-propionic acid ethyl ester was coupled with 1-Methyl-piperidine-4-carboxylic acid using isobutylchloroformate and N-methylmorpholine in DMF to give (S)-2-{(S)-3,3-Dimethyl-2-[(1-methyl-piperidine-4-carbonyl)-amino]-butyrylamino}-propionic acid ethyl ester. This was then quaternised with MeI in DCM-acetone and subsequently hydrolysed using an hydroxide resin such as Ambersep 900-OH resin.
