To a solution of 2-(2,5-dichloro-phenoxy)-nicotinic acid (59.7 mg, 0.21 mmol, 1.0 equiv; Example 31, Step 1) in dichloromethane (2 mL) was added 6-fluoro-1,2,3,4-tetrahydro-quinoline (34.9 mg, 0.23 mmol, 1.1 equiv; [CAS RN 59611-52-8]), triethylamine (42.5 mg, 59 μL, 0.42 mmol, 2.0 equiv; [CAS RN 121-44-8]) and 2-chloro-1-methylpyridinium iodide (59.0 mg, 0.23 mmol, 1.1 equiv; [CAS RN 14338-32-0]). The reaction mixture was stirred at 40° C. over night. Removal of the solvent mixture under reduced pressure and purification by preparative HPLC on reversed phase (Xterra® PrepMSC 18, 5 μm, 19×50 mm column equipped with a Gilson Liquid Handler 215 autosampler, two Rainin Dynamax® SD-300 pumps, a Sedex ELSD 75 lightscatter and a Dionex UVD 340S UV detector) eluting with a gradient of acetonitrile/water provided 27 mg (31%) of the title compound. MS (ISP): 417.4 [M+H]+.
