실험 절차

3.21 g of ethyl (2S)-3-(6-chloropurin-9-yl)-2-(naphthalene-1-sulfonylamino)propionate (Example 2) in 20 ml of abs. DMF were treated with 4.0 g of 7-(piperidin-4-yl)-1,2,3,4-tetrahydro-[1,8]naphthyridine and 3.88 g of diisopropylethylamine, and the mixture was stirred at 70° C. for 3 h. The solvent was distilled off in vacuo, the residue was taken up in EA and the mixture was extracted three times with water. The aqueous phases were extracted three times with DCM. The combined organic phases were dried over MgSO4 and filtered, and the solvent was distilled off in vacuo. For purification, the residue was chromatographed over silica gel (DCM/CH3OH/CH3COOH/H2O 95:5:0.5:0.5). Yield: 3.29 g.
