In a tube is combined (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(2,4-dichloro-phenyl)-ethyl]-amine [200 mg, 0.6 mmol, Intermediate (44)], nipecotic acid (194 mg, 1.5 mmol), K2CO3 (249 mg, 1.8 mmol) and 1-methyl-2-pyrrolidinone (2.5 mL). The tube is sealed and heated to 140° C. and stirred for 5 hours. The mixture is allowed to cool to ambient temperature, stand for 12 hours, diluted with water (20 mL) and acidified using 3M HCl. A precipitate forms and is collected by filtration and dried under high vacuum to afford 1-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-piperidine-3-carboxylic acid [121 mg, 47%, Example 73] as a solid. LCMS RT=2.15 minutes, MS: 425 (M+H). IC50=0.8 nM
