Reaction Steps

The title compound (2.99 g, 85%) was synthesized by the reaction of N-[2-(benzothiazole-2-sulfonylamino)-ethyl]-glycine ethyl ester (1.72 g, 5 mmol) and [4-N-(benzhydryloxycarbonyl)-cytosin-1-yl]-acetic acid (1.90 g, 5 mmol) as per the procedure of Example 20. 1H NMR (500 MHz; DMSO-d6) δ 11.00 (s, 1H), 8.86 (brs, 1H), 8.27 (d, 1H), 8.18 (d, 1H), 7.89 (d, 0.6H), 7.83 (d, 0.4H), 7.68˜7.61 (m, 2H), 7.45˜7.26 (m, 10H), 6.94 (t, 1H), 6.79 (s, 1H), 4.81 (s, 1.2H), 4.62 (s, 0.8H), 4.35 (s, 0.8H), 4.13 (q, 0.8H), 4.06 (s, 1.2H), 4.03 (q, 1.2H), 3.59 (t, 1.2H), 3.44˜3.39 (m, 2H), 3.21 (t, 0.8H), 1.19 (t, 1.2H), 1.13 (t, 1.8H).
