tert-Butyl 4-(methylamino)piperidine-1-carboxylate → 4-{[2-(S)-[(5-Chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propionyl]methylamino}piperidine-1-carboxylic acid tert-butyl ester

Participants

Reaction Steps

The title compound was prepared according to EXAMPLE 229 from 2-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)-propionic acid (EXAMPLE 228) and 4-methylaminopiperidine-1-carboxylic acid tert-butyl ester (Preparation 86). Purification by chromatography using dichloromethane/methanol (95:5) as the eluent gave the title compound as a pale yellow powder. m/z (ES+)=558.48 [M+H]+; RT=3.82 min.
