Chemical Properties:Light yellow Cryst

Purification Methods:

The acid is recrystallised from H2O and then from EtOH using charcoal. The amide has m 219-219.5o (from aqueous EtOH), and the methyl ester, prepared by addition of ethereal diazomethane, can be purified by sublimation in a vacuum and has m 98-99o. The acid chloride also can be sublimed in vacuo and has m 74-75o and gives the methyl ester in MeOH. [Graf J Prakt Chem 138 244 1933, Bachman & Micucci J Am Chem Soc 70 2381 1948, Garcia et al.
