合成路线2

Alkylation of delta-valerolactam (V) with tert-butyl bromoacetate in the presence of NaH provided (VI). Subsequent tert-butyl ester cleavage by means of trifluoroacetic acid furnished 2-(2-oxopiperidin-1-yl)acetic acid (VII), which was finally coupled with amine (IV) to afford the title amide.
