실험 절차

4-tert-Butyl-2-carboxymethyl-benzoic acid (90 mg, 0.38 mmol) and urea (45 mg, 0.75 mmol) were grinded and mixed in a round bottle flask, then placed into an oil bath, preheated to 145° C. The flask is kept at this temperature for 1 hour before it is cooled to room temperature. Chromatography of the residue afforded the title compound (45 mg, 55%). MS (ESI): 216.1 (M−1)−1.
