실험 절차
With stirring, a mixture of 5.24 g (16.4 mmol) of 2-chloro-4-[2-ethyl-4-(4-fluorophenyl)-1,3-thiazol-5-yl]pyridine and 25 ml benzylamine is heated at 180° C. After 16 h, the reaction mixture is concentrated under reduced pressure, the residue is taken up in 100 ml of MTBE, the resulting precipitate is filtered off and the filtrate is concentrated again. The residue is then purified by column chromatography on silica gel (cyclohexane/ethyl acetate). This gives 4.75 g (88%) of the desired product; 1H-NMR(MeCN-d3) δ: 7.91 (d, 1H), 7.49 (m, 2H), 7.29 (m, 5H), 7.07 (m, 2H), 6.45 (d, 1H), 6.39 (s, 1H), 5.83 (br.s, 1H), 4.43 (d, 2H), 3.02 (q, 2H), 1.38 (t, 3H).
