Procedure

Four (4) g; 0.16 mole of 1,2,3,4-tetrahydro-β-carboline-1,4-dicarboxylic acid (TR-8021) prepared in Example 1 was mixed with 40 ml concentrated HCl and 120 ml of water. The mixture was refluxed at 80° C. (oil-bath) for 2 hours. A white precipitate was collected by filtration, and washed with small amount of cooled water. The crude material was boiled in water, filtered through celite and cooled. The precipitate was collected and dried in the oven at 60° C. Yield: 3 g; (74%). MP 280°-281° C.
