実験手順

To a solution of ethyl 4-[N-(cyclopropylcarbonyl)-N-[2-(dimethylamino)ethyl]-amino]benzoate (106 mg; compound obtained in Reference Example 11) in ethanol (3 mL) is added 2N sodium hydroxide solution (21 μL) and the mixture is stirred at room temperature overnight. To the reaction mixture is added 2N HCl (42 μL) and the mixture is concentrated to give a crude carboxylic acid compound. To the compound is added successively methylene chloride (2 mL), 1-(3-ethoxybenzyl)-4-piperazin-1-yl-1H-pyrazolo[3,4-d]pyrimidine dihydrochloride (105 mg, compound described in WO02/79189), 1-hydroxybenzotriazole (51.7 mg), triethylamine (124.5 μL) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (73.4 mg) and the mixture is stirred at room temperature for 19 hours. The reaction mixture is diluted with chloroform (5 mL) and thereto is added a saturated sodium hydrogencarbonate solution (10 mL). After stirring, the organic layer is separated and concentrated. The resultant crude product is purified by flash column chromatography on NH-silica gel (Chromatorex NH silica gel; Fuji Silicia Chemical Ltd., Solvent; ethyl acetate:chloroform=1:0→0:1) to give 1-(3-ethoxybenzyl)-4-[4-[4-[N-(cyclopropyl-carbonyl)-N-[2-(dimethylamino)ethyl]amino]benzoyl]piperazin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine (127 mg, yield; 84%) as an amorphous powder. MS (APCI) m/z: 597 [M+H]+
