To a solution of 2-(3-trifluoromethyl-phenoxy)-nicotinic acid (200 mg, 0.71 mmol, 1.0 equiv) in anhydrous DMF (3 mL) was added 1,2,3,4-tetrahydro-quinoline (113 mg, 107 μL, 0.85 mmol, 1.2 equiv; [CAS RN 635-46-1]), N-ethyldiisopropylamine (457 mg, 617 μL, 3.53 mmol, 5.0 equiv; [CAS RN 7087-68-5]) and HATU (322 mg, 0.85 mmol, 1.2 equiv; [CAS RN 148893-10-1]). The reaction mixture was heated by microwave irradiation to 100° C. for 5 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 157 mg (56%) of the title compound. MS (ISP): 399.2 [M+H]+.
