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.
