A. Maleanilic acid
In 50ml r.b.f, put maleic anhydride 1.5g, glacial acetic acid 15ml and stirring bar. Stirred it until anhydride melt. Put aniline 1.5ml in r.b.f and stir it for 5min in room temperature(kinetic product / 1,2addition). Did suction filtration, washed it by absolute ethanol, dried it in oven for 5 min and checked yield and m.p.

Percent yield of Maleanilic acid was 96.96% and melting point was 196°C (refernece m.p of maleanilic acid is 193-196°C). Our melting point of products was similar to reference and it means our products are pure maleanilic acid. While suction filtration, we lost some products. Therefore percent yield was less than 100%.
