Procedure:
A solution of (S)-3-(2-chloropyrimidin-4-yl)-4-isopropyloxazolidin-2-one (42 mg, 0.17 mmol), (S)-4-(1-aminoethyl)phenol hydrochloride (107 mg, 0.616 mmol, 3.5 equiv) and iPr2Net (0.121 mL, 0.695 mmol, 4.0 equiv) in DMSO (1 mL) was heated at 110° C. for 3 h and at 130° C. for additional 2 h. The reaction mixture was diluted with EtOAc (8 mL) and washed with water (30 mL). After separation, the aqueous phase was extracted with EtOAc (3×8 mL). Combined organics were dried over Na2SO4, filtered and concentrated.

Procedure:
A solution of 15.7 parts of 4-[α-(p-trifluoromethylphenyl)benzyl]pyridine in 250 parts of acetic acid is heated, with agitation, at 47° C. under approximately 4 atmospheres of hydrogen and in the presence of 2 parts of platinum oxide catalyst for 2 hours. The resultant mixture is filtered, and the filtrate is stripped of solvent by vacuum distillation. The residue is poured into 3 volumes of ice water, and the mixture thus obtained is made alkaline with sodium hydroxide. This mixture is then extracted with ether. The ether extract is dried over anhydrous potassium carbonate, filtered, and the ether removed to provide 4-[(4-trifluoromethylphenyl)phenylmethyl]piperidine as an oil.

Procedure:
A solution of 3-cyclopentyl-2-(4-iodo-6-oxo-6H-pyridazin-1-yl)-propionic acid methyl ester (0.38 g, 1 mmol) in N,N-dimethylformamide (10 mL) was treated with 3-fluoro-pyridin-2-ol (0.15 g, 1 mmol) and potassium carbonate (0.16 g, 1.2 mmol). The reaction was heated at 120° C. for 4 h and then concentrated in vacuo. The residue was partitioned between water and methylene chloride. The aqueous layer was back extracted with methylene chloride. The combined organics were washed with a saturated aqueous sodium chloride solution, and then concentrated in vacuo. Chromatography (1/1 ethyl acetate/petroleum ether) afforded 3-cyclopentyl-2-[4-(3-fluoro-pyridin-2-yloxy)-6-oxo-6H-pyridazin-1-yl]-propionic acid methyl ester (0.19 g, 53%).

Procedure:
To a 100-mL round-bottomed flask was added 3-methoxybenzyl bromide (0.73 mL, 5.22 mmol, Sigma-Aldrich, St. Louis, Mo.), ethyl N-(diphenylmethylene)glycinate (1.40 g, 5.22 mmol, Acros, Pittsburgh, Pa.), 5 M sodium hydroxide (5.22 mL, 26.1 mmol) and THF (20 mL). The reaction mixture was stirred at room temperature for 2 d. After that time, the mixture was diluted with water (30 mL) and extracted with EtOAc (2×60 mL). The organic extracts were washed with saturated NaCl (30 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as light-yellow oil. Purification by silica gel chromatography, eluting with 20% EtOAc in hexanes gave ethyl N-(diphenylmethylidene)-3-methoxyphenylalaninate (1.56 g).

After stirring for 5 minutes, the reaction mixture is transferred via cannula into a solution of 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrogen chloride in dichloromethane (21 mL) maintained at 0° C. The reaction is allowed to stir and gradually warm to room temperature over 12 hours. The reaction is washed with a 5% aqueous solution of Na2CO3 (2×50 mL). The combined aqueous layers are extracted several times with dichloromethane (50 mL) and the combined organic layers washed with brine, dried, filtered and concentrated in vacuo. The crude product is purified over silica (2:1 to 1:1 hexane/ethyl acetate) to afford 1.71 g (91% yield) of the desired product as a white solid.
