実験手順

In a 20 mL vial a solution of 3-butyl-2,4-dimethylthiazol-3-ium iodide (47.92 mg, 0.16 mmol) dissolved in CH2Cl2 (0.5 mL) was added, followed by the addition of DMAP (49.24 mg, 0.40 mmol) dissolved in CH2Cl2 (0.8 mL). Then, to the solution was added 5-fluoro-2-methylbenzoyl chloride (27.6 mg, 0.16 mmol) dissolved in CH2Cl2 (0.5 mL). The vial was capped and shaken overnight at room temperature. The residue was dissolved in 1:1 DMSO/MeOH and purified by reverse phase HPLC using a method analogous to that described in Example 53 to provide the title compound. 1H NMR (500 MHz, DMSO-d6/D2O) δ ppm 0.92 (t, 3 H) 1.28-1.41 (m, 2 H) 1.57-1.68 (m, 2 H) 2.28-2.31 (m, 3 H) 2.33-2.36 (m, 3 H) 3.92-4.03 (m, 2 H) 6.09-6.15 (m, 1 H) 6.54-6.59 (m, 1 H) 7.05-7.14 (m, 1 H) 7.19-7.27 (m, 2 H);); MS (ESI) positive ion 306 (M+H).
