Procedure

0.96 g potassium-tert-butoxide are added to an ice-cooled solution of 0.39 g (S)-2-[(2-tert-butyloxycarbonylamino-propyl)amino]-3-(2-butyn-1-yl)-5-(2-cyanophenylmethyl)-3,5-dihydro-imidazo[4,5-d]pyridazin-4-one in 5 ml dimethylsulphoxide. The mixture is stirred at ambient temperature, until the solution is clear. Then 53 μl methyl iodide are added, and the solution is stirred for a further 3.5 h at ambient temperature. Then water is added to the reaction solution, the precipitate formed is separated off and washed with water. The dried precipitate is purified by chromatography through silica gel (petroleum ether/ethyl acetate 1:1).
