실험 절차

To a solution of 2-(3-chloro-4-fluoro-phenoxy)-nicotinic acid (32.1 mg, 0.12 mmol, 1.0 equiv; Example 77, Step 1) in dichloromethane (1 mL) was added 6,7-difluoro-1,2,3,4-tetrahydro-quinoline (24.4 mg, 0.14 mmol, 1.2 equiv; [CAS RN 953717-64-1]), tri-n-butylamine (111.2 mg, 143 μL, 0.60 mmol, 5.0 equiv; [CAS RN 102-82-9]) and 2-chloro-1-methylpyridinium iodide (36.8 mg, 0.14 mmol, 1.2 equiv; [CAS RN 14338-32-0]). The reaction mixture was heated by microwave irradiation to 60° C. for 15 min. 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 4.7 mg (9%) of the title compound. MS (ISP): 419.0 [M+H]+.
