Procedure
174 g (1.04 moles, 2.5 mol equivalents) of 2-(2-methoxy phenoxy)ethylamine is dissolved in 500 ml of monochlorobenzene. The temperature is raised to 125° C. under stirring. 100 g (0.42 moles) of 4-(2,3-epoxy propoxy)carbazole is slowly added in five lots during 1 hr at reflux temperature. Refluxing is then carried on for two hrs. The reaction is monitored to completion by thin layer chromatography and then cooled to 90° C. 500 ml water is then charged followed by cooling to 70° C. The pH of reaction mass is adjusted to 2.5-2.7 with 10% oxalic acid solution at 60° C.-70° C. Stirring is done for one hr at 60° C.-70° C. The reaction mass is cooled to room temp and maintained for two hrs. The material is filtered and washed with water and dried at 50° C.-60° C.
