ThenKOH solution (40 %, 2 mL) was added drop wise and theresultant mixture was stirred at room temperature for3-4 h. The precipitated product of chalcone was thencollected by filtration. The crude product was purified byrecrystallization from chloroform-methanol (1:1 v/v,10 mL) to afford (80-85 % yield) the product as yellow tolight brown needles (3a, 3b). Single crystals suitable forX-ray diffraction of both of the chalcones were obtained byrecrystallization from a saturated solution in DMSO.
