To a solution of 0.0817 g (0.233 mmole) 2-chloro-thieno[3,2-d]pyrimidine-7-carboxylic acid (5,6-dimethoxy-pyridin-2-yl)-amide in 2.33 mL of dioxane was added 0.168 mL (1.4 mmole) of cis-cyclohexane-1,2-diamine. The mixture was heated at 100 degrees for over night. Water and dichloromethane were added, separated. The aqueous layer was washed with dichloromethane twice. The organic layer was washed with aqueous sodium carbonate, 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 0.048 g of 2-(cis-2-amino-cyclohexylamino)-thieno[3,2-d]pyrimidine-7-carboxylic acid (5,6-dimethoxy-pyridin-2-yl)-amide as a light yellow solid. MH+/Z=429.
