Yield: 70%

Reaction Conditions:

with propionic acid in diethyl ether at 60; for 0.5 h;

Steps:

2.4. Synthesis of H2TMP and H2TTP
The two starting compounds i.e. H2TMP and H2TTP were synthesizedaccording to the modified Adler's method [25]. Pyrrole(20 mmols) and para-substituted benzaldehydes (20 mmols) wereadded to the propionic acid solutions (50 ml) in a 250 ml roundbottomed flasks fitted with water condensers. The reaction mixtureswere then allowed to reflux for half an hour at 60° C, as shown in Scheme 2. After the completion of the reaction, the reaction mixtures were allowed to cool at room temperature and then stored in refrigerator for 2 h. The shiny purple crude products of H2TMP and H2TTP were then filtered and the residues were airdried completely. The crude products were then subjected to their purifications on basic alumina columns using methanol in case of H2TMP and chloroform in case of H2TTP as eluting solvents. Thepurified compounds were finally recovered by the evaporation ofthe organic solvents.
