The resulting residue is purified by silica gel column chromatography (hexane : ethyl acetate = 19: 1-->9: 1) to give tert-butyl 4-{2- [(3,5-dichloro-benzyl)-(5'-isopropyl-2'-methoxy-4-trifluoromethyi-biphenyl- 2-ylmethyl)-amino]-pyrimidin-5-yloxy}-butyrate (184mg). MS (m/z):720/718 [M+H]+. |

| 21% | [199] Step 1. Alkylation of 1 with A to give 2; [200] Sodium hydride (40 mg of a 60percent dispersion in oil, 1.0 mmol) was added to a solution of 1 (200 mg,0.87 mmol) in DMF (5 mL). After 30 min at room temperature, a solution of A (commercially available fromAcros Chemical, 187 mg, 0.96 mmol) in DMF (3.7 mL) was added, followed by tetrabutylammonium iodide(32 mg, 0.087 mmol). The mixture was heated at 400C for 18 h then cooled to room temperature. The mixture was partitioned between EtOAc (50 mL) and water (50 mL). The phases were separated and the aqueous phase was extracted with EtOAc (2x20 mL). The combined organic phase was washed with brine(50 mL), dried (MgSO,)), filtered and concentrated in vacuo. The crude residue was purified by flash column chromatography on 12 g silica (hexane - EtOAc, gradient) to afford 70 mg (21percent) of 2. |

| 48% | To a solution of NaH (60percent in mineral oil, 0.022 g, 0.55 mmol) in dry DMF (1 mL) cooled to 0° C. is added cis-4-[4-(1-methylpyrazole-4-yl)pyrimidin-2-yl]-2,6-diethylpiperidine-1-carboxylic acid tert-butyl ester (0.15 g, 0.36 mmol). After stirring the resulting solution at room temperature for 30 minutes, 3,5-dichlorobenzylchloride (0.13 g, 0.54 mmol) is added, and the resulting mixture is stirred for 2 hours. The mixture is quenched with 1M HCl, then extracted twice with ethyl acetate. The combined organic layer is washed with brine, dried over MgSO4, filtered, concentrated under reduced pressure. The obtained residue is purified by silica gel column chromatography to afford cis-4-[4-(1-methylpyrazole-4-yl)pyrimidin-2-yl](3,5-dichlorobenzyl)amino}-2,6-diethylpiperidine-1-carboxylic acid tert-butyl ester (0.10 g, 48percent). 1H-NMR (400 MHz, CDCl3): 0.85 (t, 6H), 1.40-1.55 (m, 4H), 1.48 (s, 9H), 1.75-1.83 (m, 2H), 2.10-2.19 (m, 2H), 3.95 (s, 3H), 4.07-4.14 (m, 2H), 4.73 (s, 2H), 4.73-4.83 (m, 1H), 7.12 (d, 2H), 7.22 (t, 1H), 7.53 (s, 1H), 7.66 (s, 1H), 8.43 (s, 2H). |
