Following the procedure as described in Example 3, making variations only as required to use n-hexylamine in place of isoamylamine to react with 5-[4-(2-trifluoromethylbenzoyl)piperazin-1-yl][1,3,4]thiadiazole-2-carboxylic acid ethyl ester, the title compound was obtained as a white solid (0.62 g, yield 48%). 1H NMR (300 MHz, CDCl3) δ 7.70-7.75. (m, 1H), 7.52-7.65 (m, 2H), 7.30-7.36 (m, 1H), 6.98-7.06 (m, 1H), 4.00-4.09 (m, 1H), 3.81-3.91 (m, 1H,), 3.62-3.70 (m, 2H), 3.48-3.55 (m, 2H), 3.29-3.43 (m, 4H), 1.52-1.62 (m, 2H), 1.20-1.40 (m, 6H), 0.80-0.90 (m, 3H). 13C NMR (75 MHz, CDCl3) δ 174.5, 167.6, 158.2, 156.0, 134.0, 133.9, 132.4, 129.6, 129.0, 127.0, 126.9, 121.8, 49.5, 49.0, 45.9, 40.7, 39.7, 31.4, 29.4, 26.5, 22.5, 14.0.
