Reaktionsschritte

To a solution of 6-bromomethyl-2,4-pteridinediamine hydrobromide (41.6 mg, 0.124 mmol) in anhydrous N,N dimethylacetamide was added 1-aminomethyl adamantane (35.43 ul, 0.2 mmol). The reaction mixture was stirred at 50° C. overnight. The crude product was poured into saturated bicarbonate solution. The resulted precipitate was collected and purified by preparative HPLC. 12.7 mg product was obtained. Yield: 40%; 1H NMR (500 MHz, DMSO-d6): δ 1.56754–1.67101(m, 13H), 1.96741(s, 2H), 2.71139(s, 2H), 4.49166(s, 2H), 8.89918(s, 1H); ESI-MS: m/z 340 (M++1)
