실험 절차

The similar procedure as described in example 35 was used, starting from 4-(6-formyl-quinolin-4-yloxy)-piperidine-1-carboxylic acid tert-butyl ester, 2-Amino-thiazol-4-one (example 48b), sodium acetate and acetic acid to obtain 4-{6-[2-amino-4-oxo-4H-thiazol-(5Z)-ylidenemethyl]-quinolin-4-yloxy}-piperidine-1-carboxylic acid tert-butyl ester as a yellow solid. Purification was performed with flash chromatography (Merck silica gel 60, 230-400 mesh, 1%-5% methanol in dichloromethane for 30 min. LC-MS m/e 455.5 (MH+).
