To the residue glycine (0.129 g, 1.72 mmol) and sodium methoxide methanol solution (0.5 N, 2.88 mL, 1.44 mmol) were then added. The mixture was then refluxed overnight, cooled, and concentrated. The residue was dissolved in water (30 mL), and the solution was washed with ethyl acetate (3×20 mL). After the solution was acidified to pH 1-2 with 2N HCl, a light yellow solid precipitated, that was collected by filtration and then dried in vacuo to give 23.5 mg of the title compound.

Procedure:
35.1 g (0.15 mol) of 2-acetylamino-4-nitrophenol, in the form of the potassium salt, are introduced into 105 ml of dimethylformamide and the mixture is then heated to 60° C., whilst stirring. 25.8 g (0.21 mol) of γ-dimethylaminopropyl chloride are then added; the reaction medium is heated at 90° C. for 210 minutes and is then poured into 750 g of iced water to which 40 ml of 1 N sodium hydroxide solution have been added. The expected product is extracted with methyl isobutyl ketone. After the methyl isobutyl ketone has been driven off in vacuo, the expected product is obtained in the form of an orange oil which crystallises rapidly (melting point: 69° C.).

Procedure:
A solution of 3-[2-biphenyl-4-yl-1-(4-chloro-phenyl)-6-oxo-1,6-dihydro-purin-9-yl]-benzoic acid (40 mg, 0.077 mmol) in SOCl2 (1 mL) was heated at 70° C. for 1 h. The reaction mixture was allowed to cool to room temperature and poured into a 50% aqueous solution of NH4OH (15 mL). The resulting mixture was diluted with H2O and extracted with CH2Cl2. The combined organics were dried (MgSO4), filtered, and concentrated. The crude material was purified by flash column chromatography (silica gel, 5% MeOH/CH2Cl2) to give the title compound 3-[2-biphenyl-4-yl-1-(4-chloro-phenyl)-6-oxo-1,6-dihydro-purin-9-yl]-benzamide as a white solid. 1H NMR (CDCl3) δ (ppm) 8.67 (s, 1H), 8.29 (t, 1H), 8.15 (br s, 1H), 8.02 (d, 1H), 7.98 (d, 1H), 7.71 (t, 1H), 7.64 (d, 2H), 7.58 (d, 3H), 7.46 (br s, 2H), 7.44 (m, 6H), 7.37 (m, 1H); HPLC-MS calculated for C30H20ClN5O2 (M+H+): 518.1.

Procedure:
To a solution of 3-hydroxy-1-(pyridin-2-yl)cyclobutanecarbonitrile (WO 2007/060484)(10.996 g, 63.1 mmol) in dry DCM (100 mL) and pyridine (20.59 mL, 252 mmol), was added (with stirring and cooling in an ice water bath) methane sulfonyl chloride (4.88 mL, 63.1 mmol). The mixture was stirred at RT for 25 hours. The solvent was removed at reduced pressure, and the residue was partitioned between EtOAc and aqueous NaHCO3. The organic phase was washed with aqueous NaHCO3 and was concentrated at reduced pressure. The residue was eluted through a short pad of silica gel (eluent 30%-50% EtOAc/hexane). The solvent was removed, and the resulting oil was crystallized from toluene on dilution with hexane to afford the title compound as a 3:1 mixture of geometrical isomers (assessed by NMR).
