Procedure:
To a stirred solution of 1-(2-amino-pyridin-4-ylmethyl)-1H-benzo[d][1,3]oxazine-2,4-dione (600 mg, see preparation 7b) in pyridine (7 ml) was added methanesulfonyl chloride (280 mg) and the reaction mixture was stirred at room temperature for 15 hours. The solvent was evaporated under reduced pressure and the residue was dissolved in EtOAc and washed with water and brine. The organic layer was dried (MgSO4) and evaporated under reduced pressure. The remaining solid yellow material was dissolved in a mixture of hot EtOAc (50 ml) and DMF (4 ml). On cooling a solid material formed, that was isolated by filtration and dried under vacuum, affording N-[4-(2,4-dioxo-4H-benzo[d][1,3]oxazin-1-ylmethyl)-pyridin-2-yl]-methanesulfonamide. Step 2: This anhydride intermediate was converted into the title compound by reaction with O-cyclopentylmethyl-hydroxylamine hydrochloride (see preparation 66), using general procedure 1A. 13C-NMR (DMSO-d6) δ 166.8, 152.9, 152.6, 148.3, 132.4, 127.9, 115.2, 114.8, 113.3, 111.4, 110.1, 79.4, 45.0, 41.5, 37.6, 28.9, 24.9.

Procedure:
Into a 100-mL round-bottom flask was placed 2-ethenylbenzonitrile (2.73 g, 21.14 mmol, 1.00 equiv), sodium bicarbonate (1.77 g, 21.07 mmol, 4.61 equiv), dichloromethane (20 mL) and water (20 mL). Then m-CPBA (10.9 g, 63.16 mmol, 2.25 equiv) was added at 0° C. in several batches. The resulting solution was stirred overnight at room temperature and then concentrated under vacuum. The residue was applied onto a silica gel column with PE/EA (50:1). Purification afforded 400 mg (13%) of 2-(oxiran-2-yl)benzonitrile as a yellow oil.

Procedure:
100 mg of 3,5-dichloro-4-[(3-isopropyl-1H-indol-5-yl)oxy]aniline (Example IV) are heated to reflux with 49 mg of sodium acetate and 50 mg of ethyl bromoacetate in 5 ml of ethanol for 17 hours. A further 21 mg of ethyl bromoacetate are added and the mixture is refluxed for 2 hours. The solvent is removed in vacuo, the residue is taken up with water and dichloromethane, the organic phase is washed with saturated sodium chloride solution, dried and the solvent is removed in vacuo. Chromatographic purification (cyclohexane/ethyl acetate) affords 22 mg of ethyl N-{3,5-dichloro-4-[(3-isopropyl-1H-indol-5-yl)oxy]phenyl}glycinate.

Procedure:
To a THF (20 ml) solution of methyl quinoline-6-carboxylate (984 mg, 5.26 mmol, J. O. C., 2002, 67, 7890) was added t-butylmagnesium chloride in THF (15.8 ml, 1M solution) dropwise at −78° C. over 30 min. The mixture was stirred at −78° C. for 30 minutes and at −40° C. for 30 minutes, then at room temperature for 1 hour. The reaction was quenched with saturated ammonium chloride aqueous solution (100 ml) and extracted with ethyl acetate (100 ml×2) which was dried over sodium sulfate. Then, filtration and evaporation gave a yellow oil, which was dissolved in THF (50 ml) and manganese dioxide (1.83 g 15.8 mmol) was added. After the mixture was stirred at room temperature for 2.5 hours, the precipitate was removed through a pad of celite and washed with ethyl acetate. The filtrate was concentrated and purified through silica gel column chromatography, eluting with Hexane/Ethyl acetate (20:1), to furnish the title compound (348 mg, 27% yield) as a white solid. 1H NMR (300 MHz, CDCl3) δ 1.48 (9H, s), 3.99 (3H, s), 7.59 (1H, d, J=8.8 Hz), 8.08 (1H, d, J=8.8 Hz), 8.17 (1H, d, J=8.8 Hz), 8.26 (1H, dd, J=2.2, 8.8 Hz), 8.55 (1H, d, J=2.2 Hz).
