To a solution of 200 mg (3aSR,10RS)-2-(2-Bromo-ethyl)-6-chloro-10-(3-hydroxy-phenyl)-3a-methyl-3a,4,9,10-tetrahydro-2,9,10a-triaza-cyclopenta[b]fluorene-1,3-dione (example 26) in 3 ml methanol are added 1.2 ml of a 7 M solution of ammonia in methanol. The mixture is heated in a sealed tube to 140° C. for 1 h using a microwave reactor. The solvent is removed under reduced pressure. Water is added and the mixture is extracted with ethyl acetate. The organic layer is dried with magnesium sulfate. The solvent is removed under reduced pressure. The crude product is purified by preparative HPLC. 24 mg of the title compound are obtained. MS: m/z (MH+)=425.1
