関与物質

反応手順

To a solution of N2-Benzyl-5-(1H-tetrazol-5-yl)pyrimidine-2,4-diamine (27 mg, 0.1 mmol) in 1 mL of DCE, DIPEA (0.3 mmol, 3.0 eq.) was added followed by thiophene-2-carbonyl chloride (0.15 mmol, 1.5 eq.). The reaction was stirred at room temperature for 2 hours. The crude reaction mixture was concentrated down in vacuo, and the residue redissolved in ethylacetate. This organic solution was extracted several times with water, dried with magnesium sulfate, filtered and concentrated. The residue was purified by reverse phase HPLC to give 4.8 mg of the desired compound. 1H-NMR (400 MHz, d6-DMSO): δ 9.07 (t, 1H), 7.81 (dd, 1H), 7.77 (dd, 1H), 7.36-7.29 (m, 4H), 7.28-7.23 (m, 1H), 7.16 (t, 1H), 4.45 (d, 2H). MS (EI) for C17H14N8OS: 379 (M+H).
