Chapter – 5 Synthesis and Characterization….. Above outcome of the synthetic aspect was further proved by 1 H, 13 C NMR (APT 25) and X-ray crystallography. The crystal structure and all data are included. 5.14 CONCLUSION In this chapter, a simple and fast method was developed for the preparation of novel C-Mannich bases of aryl amino coumarin using formaldehyde solution and different secondary amines for the first time. APT- 25 experiment has proved the possible mechanistic path governing this reaction, which is probably hitherto unknown in literature furthermore no report of other method for optimization for the synthesis of end products is found in literature.
