Versuchsvorschrift

To a solution of 0.047 g (0.134 mmole) 2-chloro-thieno[3,2-d]pyrimidine-7-carboxylic acid(2,4-dimethoxy-phenyl)-amide in 1.34 mL of dioxane was added 0.0967 mL (0.806 mmole) of (cis-cyclohexane-1,2-diamine. The mixture was heated at 100 degrees for over night. Dichloromethane was added and washed with aqueous sodium bicarbonate. The aqueous layer was washed twice with dichloromethane. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-0.7 N ammonia solution in methanol (gradient 100:0-90:10) gave 0.052 g of 2-(cis-2-amino-cyclohexylamino)-thieno[3,2-d]pyrimidine-7-carboxylic acid (2,4-dimethoxy-phenyl)-amide as a yellow solid. MH+/Z=428
