Procedure

5 mg (14 μm) of the L-malic salt was dissolved in a mixture of 1 ml H2O, 3.5 mg (3 meq) NaHCO3, and 1 ml acetonitrile. 3.2 mg (14 μm) 3,5-dinitrobenzoyl chloride was added and the reaction stirred for 16 hr at room temperature. After 5 ml H2O was added, the reaction was vacuum filtered and washed with H2O (2×1 ml portions), cold isopropanol (2×1 ml portions) and diethyl ether (2×2 ml) to isolate 2.5 mg of the 3,5-dinitrobenzamide (85 area % by gradient reverse phase HPLC).

Workup

  1. filtrationfiltered
  2. washwashed with H2O (2×1 ml portions), cold isopropanol (2×1 ml portions) and diethyl ether (2×2 ml)
