Versuchsvorschrift

In 1 ml of chloroform was dissolved 100 mg of (3aR,6aR)-1,3-dibenzyl-hexahydro-4H-thieno[3,4-d]imidazol-2,4-dione, 0.5 ml of pyridine was added to the solution, and the resulting mixture was stirred at room temperature for 23 hours. The reaction mixture was successively washed with 2M hydrochloric acid, water, a saturated sodium bicarbonate solution, and saturated brine. The organic layer was dried and then concentrated. By adding isopropyl ether, precipitated crystal was collected by filtration to give 75.1 mg of (3aS,6aR)-1,3-dibenzyl-hexahydro-4H-thieno[3,4-d]imidazol-2,4-dione.
