Reaction Steps

To a solution of 2-(2,5-dichloro-phenoxy)-nicotinic acid (42.6 mg, 0.15 mmol, 1.0 equiv; Example 31, Step 1) in anhydrous DMF (1.5 mL) was added 7-chloro-1,2,3,4-tetrahydro-quinoline hydrochloride (33.7 mg, 0.17 mmol, 1.1 equiv; [CAS RN 90562-34-8]), triethylamine (30.4 mg, 42 μL, 0.3 mmol, 2.0 equiv; [CAS RN 121-44-8]) and HATU (62.7 mg, 0.17 mmol, 1.1 equiv; [CAS RN 148893-10-1]). The reaction mixture was heated by microwave irradiation to 110° C. for 30 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 6 mg (10%) of the title compound. MS (ISP): 435.0 [M+H]+.
