Vorschrift

Trichloroethyl chloroformate (1.06 mL, 7.7 mmol) is added over a 10 minute period to a solution of 9,10-dihydro-10-methyl-9-(1-methyl-4-piperidinyl)acridine (453 mg, 1.55 mmol) [(Tetrahedron Letters, 29, 5701 (1988)] and triethylamine (649 μl, 4.65 mmol) in 20 mL of dry toluene at 85° C. The reaction is worked up after 30 minutes by extracting with EtOAc and washing with a 10% NaOH solution. The crude product is obtained after the solvent is removed.
