    • 3 (0.5 mol) was added drop wise and allowed stirring for 10 min. The temperature was increased to 80°C and after completion of reaction (monitored by TLC) the mixture was poured into ice cold sodium acetate (0.2 mol) solution and the solid was filtered out and purified by column chromatography using ethyl acetate/petroleum ether mixture (3:1 v/v) to to yield pure 2a-h.
