Reaction Conditions:
with palladium 10% on activated carbon;hydrogen in methanol; for 5 h;
Steps:
f f) Preparation of EDDA from DAS.
DAS (0.1 g, 0.48 mmol) and 10% Pd/C (0.22 g) was mixed with methanol (5 ml) in a two neck round bottom flask and H2 gas was bubbled into the mixture while stirring. After 5 h the reaction mixture turned pink from orange. The reaction mixture was filtered and solvent was evaporated to get shiny pinkish crude product in 99% yield which was recrystallized using ethanol to get pink colored crystal. The specifications were as follow: 1H NMR (400 MHz, DMSO-d6, δ, ppm): 2.61 (s, 4H), 4.79 (s, 2H), 6.49 (d, 2H, J = 8 Hz), 6.85 (d, 2H). 13C NMR (100 MHz, DMSO-d6, δ, ppm): 37.1, 113.9, 128.7, 129.0, 146.3. Mass: m/z = 213.14217 (experimental), 212.1313 (calculated). Melting point: 137 °C.
