Procedure
To a suspension of 2 g of 3-(2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)propionic acid in 40 ml of t-butanol were added 2.1 ml of DPPA and 2.6 ml of triethylamine, followed by heating and refluxing at 100° C. for 18 hours. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (elution solvent: chloroform-MeOH) to obtain 1.832 g of t-butyl[2-(2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)ethyl]carbamate as an orange solid.
