Versuchsvorschrift

To a solution of (-)(2aR,4S)-6-acetyl-4-[di-(cyclopropylmethyl)amino]-1,2,2a,3,4,5-hexahydrobenz[cd]indole (2.5 g, 7.7 mmol) and triethylamine (1.1 ml, 8 mmol) in 90 ml CH2Cl2 was added dropwise a solution of 2,2,2-trichloroethylchloroformate (1.7 g, 8 mmol) in 10 ml CH2Cl2. The reaction mixture was stirred at room temperature for one hour and then extracted with water and 1N HCl. The organic solution was washed with a saturated NaHCO3 solution and a saturated brine solution, dried over MgSO4 and then concentrated to dryness in vacuo to give 3.1 g of the 1-carbamylindoline.
