Procedure
150 mg (0.51 mmol) of isopropyl 6-chloro-3-ethylquinolin-2(1H)-one-4-carboxylate (Example 10) are reacted with Lawesson's reagent according to the process described in Example 5 (reaction time 5 hours at reflux temperature) and purified by means of chromatography on silica gel as indicated above (mobile phase: n-heptane/ethyl acetate=2/1).
Workup
- customdescribed in Example 5 (reaction time 5 hours at reflux temperature)
- custompurified by means of chromatography on silica gel as indicated above (mobile phase: n-heptane/ethyl acetate=2/1)
