A mixture of the compound (II) (12.0 g), 3,4,5,6-tetrahydrophthalic anhydride (7.56 g), piperidine (0.18 g), propionic acid (0.30 g) and toluene (24 g) was heated under reflux for 5 hours, during which water as by-produced was azeotropically removed. To the reaction mixture, toluene (24 g) and water (24 g) were added, and the organic layer was separated and concentrated under reduced pressure. To the residue, water (18 g) and methanol (33 g) were added, and the precipitated crystals were collected by filtration to give N-[4-chloro-2-fluoro-5-(pentyloxycarbonylmethyloxy)-phenyl]-3,4,5,6-tetrahydrophthalimide (Compound (I)) (16.1 g). By the use of a high speed liquid chromatography, the purity of the compound (I) as the major product and the amount of the by-produced 4-chloro-2-fluoro-5-(pentyloxycarbonylmethyloxy)acetanilide (hereinafter referred to as "N-acetyl compound") as a contaminant were determined according to the inner standard method and the area comparison method, respectively.

Procedure:
To a solution of Intermediate 8B (717 mg, 2.184 mmol) and (S)-2-methylpropane-2-sulfinamide (529 mg, 4.37 mmol) in THF (10 mL) was added tetraethoxytitanium (1993 mg, 8.74 mmol) in THF (20 mL). The resulting mixture was reflux for 5 h. TLC (20% EtOAc in hexane) indicated the starting ketone was completely consumed. The solvent was evaporated to afford a yellow oil. This yellow oil was dissolved in EtOAc and then washed with saturated NaHCO3 (25 mL) and a large amount of white precipitation formed which was removed by filtering through a bed of Celite®. The white precipitation was rinsed with EtOAc. The combined EtOAc solution was washed again with saturated NaHCO3, dried (MgSO4) and concentrated. The crude product was purified by silica gel chromatography (40 g silica gel, eluted with EtOAc in hexanes) to afford Intermediate 8C (620 mg, 66%).

Procedure:
219.2 mg (0.76 mmol) 2-Piperidine-4-ylquinoxaline are dissolved in 5.5 mL NMP. After addition of 0.2 mL triethylamine the reaction mixture is stirred for one hour. 200 mg (0.64 mmol) 4-(2-Methyl-6-phenyl-imidazo[1,2-a]pyrimidin-7-yl)benzaldehyde and 0.06 mL acetic acid are added. The reaction mixture is stirred overnight at room temperature. 148 mg (0.7 mmol) NaBH(OAc)3, are added in portions and the reaction mixture is stirred at room temperature for 18 hours. Additionally 75 mg NaBH(OAc)3 and 0.03 mL acetic acid are added and the stirring is continued for four days. The reaction mixture is treated with saturated NaHCO3 and vigorously stirred for one hour. The precipitate is filtered off, washed with water and dried. This solid is treated three times with each 20 mL dichloromethane. After filtration of the combined dichloromethane extracts the filtrate is evaporated and the residue purified by chromatography on silica gel (dichloromethane/methanol). After an additional purification by HPLC 84 mg (25.8%) of the pure product are obtained.
