Versuchsvorschrift

A solution of 7-(methyloxy)-1-(2-oxiranylmethyl)-3,4-dihydro-1,8-naphthyridin-2(1H)-one (428 mg, 1.829 mmol) and 1,1-dimethylethyl 4-piperidinylcarbamate (366 mg, 1.829 mmol) in DMF (2 ml) under argon was heated at 120° C. for 1 h. The mixture was then evaporated and chromatographed (0-10% methanol/DCM) to give the product as a yellow oil (301 mg, 38%).
