実験手順
42-3 (0.36 g, 1.18 mmol), sodium hydride (0.094 g, 2.35 mmol) and 2-chloro-1,3-thiazole-5-carbonitrile 2-2 (0.17 g, 1.18 mmol) were treated as in Scheme 4 above. The reaction was cooled, quenched with methanol and water, evaporated to dryness and partitioned between methylene chloride, methanol and water. The organic layers were evaporated to dryness and purified on a C18 preparative hplc column and isolated via lyophilization to afford 42-4. Hi-Res MS: calc: 415.1659 found: 415.1638. 1H-NMR (CD3OD): 8.44(s, 1H); 8.01(s, 1H); 6.20(s, 1H); 4.36(s, 2H); 4.05(br s, 2H); 3.88(br s, 2H); 3.82(m, 2H); 3.76(m, 2H); 3.71(m, 2H); 3.56(m, 4H); 3.25(br s, 2H).
