Procedure

3.30 g of racemic 3-(3,4-dichlorophenyl)-2,6-dioxopiperidine-3-propionic acid are placed in 20 ml of an aqueous solution of aqueous ammonia at 30% and stirred at room temperature. After 2 hours, the solution is degassed under vacuum to remove the excess aqueous ammonia and then diluted to 50 ml with water. The medium is slowly acidified to pH 2-3 with 1 N HCl. The precipitate formed is filtered, drained and then dried over KOH to give 3.13 g of the expected compound.
