실험 절차

Following the procedure as described in Example 27, making variations as required to replace N-(1-benzylimidazolidin-2-ylidene)cyanamide with 2-benzyl-1,2,5-thiadiazolidine 1,1-dioxide to react with 2-bromo-4-methyl-N-(pyridin-3-ylmethyl)thiazole-5-carboxamide, the title compound was obtained as a colorless solid in 79% yield: mp 140-142° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, DMSO-d6) δ 8.68 (t, J=5.8 Hz, 1H), 8.49-8.43 (m, 2H), 7.67 (d, J=7.8 Hz, 1H), 7.39-7.28 (m, 6H), 4.37 (d, J=5.8 Hz, 2H), 4.26 (s, 2H), 3.46 (t, J=6.6 Hz, 2H), 3.99 (t, J=6.6 Hz, 2H), 2.46 (s, 3H); 13C NMR (75 MHz, DMSO-d6) δ 161.3, 157.2, 152.9, 149.3, 148.5, 135.6, 135.2, 129.6, 129.0, 128.8, 128.5, 124.0, 119.6, 51.3, 46.0, 44.7, 40.9, 17.5; MS (ES+) m/z 444.3 (M+1).
