Chapter – 2 Microwave assisted simple and fast…..
2. Six protons of three methylene carbons (C3, C5 and C7) gave multiplet
at 2.83 δ ppm.
3. Two protons of methylene carbon (C9) of propyl chain gave triplet at
3.73 δ ppm.
4. Four protons of two morpholinyl methylene carbons (C2 & C6) gave
triplet at 4.52 δ ppm.
5. Two aromatic protons of C15 and C17 methine groups gave multiplet at
6.63 δ ppm while another two aromatic protons of C16 and C18 methine
groups gave multiplet at 7.00 δ ppm.

2.61 δ ppm.
2. Four protons of two morpholinyl carbon atoms (C3 & C6) gave triplet at
3.95 δ ppm.
3. Two protons of methylene carbon atom (C9) gave singlet at 4.47 δ
ppm.
4. Two aromatic protons of C15 and C17 methine groups gave multiplet at
6.63 δ ppm while another two aromatic protons of C16 and C18 methine
groups gave multiplet at 7.00 δ ppm.
2.6.4 ELEMENTAL ANALYSIS
Elemental analysis of the synthesized compounds was carried out on
Vario EL Carlo Erba 1108 which showed calculated and found percentage
values of Carbon, Hydrogen and Nitrogen in support of the structure of
synthesized compounds. The spectral and elemental analysis data are given
for individual compounds.
