反応手順
0.278 g. of 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2-yl)-propionic acid is added to a solution of 0.084 g. of sodium bicarbonate in 2 ml. of water. About 20 ml. of benzene is added and the mixture evaporated to dryness. This process is repeated several times, and the residue is recrystallized from methanol/ether to afford sodium 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2-yl)propionate (m.p. 145°-148° C). By employing 0.327 g. of potassium bicarbonate in place of the sodium bicarbonate above, there is obtained potassium 2-(5-oxo-5H-dibenzo[a,d]cyclohepten-2yl)propionate.
