Procedure

To the mixture of N-[2-(benzothiazole-2-sulfonylamino)-ethyl]-glycine ethyl ester (172 mg, 0.5 mmol), [6-N-(4-methoxybenzyloxycarbonyl)-adenin-9-yl]-acetic acid (179 mg, 0.5 mmol), and HBTU (190 mg, 0.5 mmol) in DMF (2 ml) was added diisopropylethylamine (0.09 ml, 0.5 mmol) at ambient temperature. The resulting reaction mixture was stirred for 2 h at the same temperature and 1N HCl was added to the reaction mixture. The resulting precipitate product was filtered off, washed with water, and dried in vacuo to give the title compound as a white solid (0.35 g, 97%). 1H NMR (500 MHz; DMSO-d6) δ 8.97 (t, 0.6H), 8.76 (t, 0.4H), 8.64 (s, 0.4H), 8.60 (s, 0.6H), 8.53 (d, 1H), 8.28 (m, 1H), 8.17 (d, 1H), 7.66 (m, 2H), 7.40 (d, 2H), 6.95 (d, 2H), 5.41 (s, 1.2H), 5.20 (s, 0.8H), 5.18 (s, 2H), 4.46 (s, 0.8H), 4.18 (q, 0.8H), 4.08 (s, 1.2H), 4.03 (q, 1.2H), 3.75 (s, 3H), 3.70 (q, 1.2H), 3.48 (q, 1.2H), 3.42 (t, 0.8H), 3.22 (q, 0.8H), 1.24 (t, 1.2H), 1.13 (t, 1.8H).
