Following a similar N-alkylation procedure described in example 6, the (2-oxo-1,2,3,4-tetrahydro-quinolin-3-yl)-acetic acid methyl ester (0.99 mmol) is alkylated with tert-butyl bromoacetate to give (1-tert-butoxycarbonylmethyl-2-oxo-1,2,3,4-tetrahydro-quinolin-3-yl)-acetic acid methyl ester as a colorless oil, after purification by silica gel chromatography (hexane/EtOAc). Yield: 89%. MS: (ES+): 356.2 [M+23].
