To this solution were added, in succession, N,N-diisopropylethylamine (0.684 mL, 3.93 mmol) and solid O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.496 g, 1.31 mmol). The resulting reaction mixture was stirred at that temperature for 25 minutes; solid 4,4-bis-(4-fluoro-phenyl)-butylamine monohydrochloride (0.390 g, 1.31 mmol) was then added. After stirring for, sequentially, 15 minutes at 0° C. and 30 minutes at ambient temperature, reaction mixture was mixed with 60 mL of diethyl ether; the resulting mixture was successively washed with saturated aqueous NaHCO3 solution (2×60 mL), brine (2×60 mL), and was dried over Na2SO4. The solution was concentrated in vacuo affording an viscous oil. The crude product was further purified by flash chromatography (70% EtOAc in hexane) and treated with ethereal HCl. Subsequent concentration in vacuo and drying under vacuum provided 0.432 g (63%) of the pure titled compound as a white foam; mp 75-92° C. APCI-MS m/z 473.4 (MH+).

Procedure:
A suspension of methyltriphenylphosphonium bromide (pre-dried under vacuum at 60° C., 3.80 g) in THF (60 mL) was cooled to 5° C., under nitrogen. Potassium bis-(trimethylsilyl)amide (0.5M in toluene, 21.3 mL) was added and the suspension was warmed to room temperature and stirred for 45 minutes. It was cooled to −78° C. and a solution of methyl 6-(benzenesulfonylmethyl)-3-(2-formylfuran-3-yl)-2-hydroxybenzoate (Intermediate 28, 1.42 g) in THF (40 mL) was added and the mixture was warmed to room temperature and stirred for 2.5 hours. Ethyl acetate and a saturated aqueous solution of ammonium chloride were added to the mixture and the organic layer was separated, washed with brine, dried (Na2SO4) and filtered. The filtrate was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of ethyl acetate and cyclohexane with a gradient of 15-35% to give methyl 6-(benzenesulfonylmethyl)-2-hydroxy-3-(2-vinylfuran-3-yl)-benzoate (1.24 g) as a white solid.

Procedure:
7-(4-(1-Methylpiperidin-4-yl)phenyl)-5-(1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidine (0.130 g, 0.363 mmol) and 3-cyclopentylacrylonitrile (Table 1, compound g; 0.220 g, 1.81 mmol) were suspended in DMF (10 mL) and 2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepine (0.2169 mL, 1.451 mmol) added in one portion. The reaction mixture was stirred at ambient temperature for 66 hours. The reaction mixture was partitioned between saturated aqueous 1 N NaOH and EtOAc.

Procedure:
To (2S,4R)-2-carbamoyl-4-methanesulfonyloxy-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (3 g) was added N,N-dimethylformamide dimethylacetal (3 ml) and the mixture was stirred at 120° C. for 1 hour. The mixture was poured into a mixture of ethyl acetate and dichloromethane, washed with water and brine successively, and evaporated in vacuo to give (2S,4R)-4-methanesulfonyloxy-2-[N-(N,N-dimethylaminomethylene)carbamoyl]-1-(4-nitrobenzyloxycarbonyl)pyrrolidine. The compound obtained above was dissolved in acetic acid (30 ml) and to this solution was added hydrazine hydrate (0.36 ml) at room temperature. After stirring at the same temperature for 2 hours, the mixture was poured into water and ethyl acetate. The organic layer was washed with saturated aqueous sodium bicarbonate and brine successively, dried over magnesium sulfate, and evaporated in vacuo. The oily residue was subjected to a column chromatography on silica gel (90 g) eluting with a mixture of methanol and dichloromethane (1:20 V/V) to give (2S,4R)-4-methanesulfonyloxy-1-(4-nitrobenzyloxycarbonyl)-2-(1H-1,2,4-triazol-3-yl)pyrrolidine (1.5 g).
