Phenidic acid

Phenidic acid, or Ritalinic Acid, or Evitalinic Acid is a portmanteau of 2-{Phen}yl-2-(p{i}peri{d}in-2-yl) acet{ic} {acid}. It is used to make Methylphenidate (Ritalin) and Ethylphenidate (Evitalin) by reacting it with methanol and ethanol. 2-Phenyl-2-(piperidin-2-yl) acetic acid is awesome!

Steve: I reacted Phenidic acid and Methanol to make Methylphenidate (Ritalin). I used the rest of the Phenidic acid to make Ethylphenidate (Evitalin).
