HCID 234980934-Chloro-7-fluoro-6-[2-(4-morpholinyl)ethoxy]-3-quinolinecarbonitrile収率 57%

実験手順

Following the procedure used to prepare Reference Example 14, reaction of 4-chloro-7-fluoro-6-hydroxy-3-quinolinecarbonitrile with triphenyl phosphine, diethyl azodicarboxylate and 4-(2-hydroxyethyl)morpholine provides 4-chloro-7-fluoro-6-(2-morpholin-4-ylethoxy)-3-quinolinecarbonitrile in 57% yield. An analytical sample is obtained by preparative thin layer chromatography eluting with 1% methanol in ethyl acetate, mp 163-164° C.
