Procedure:
In a reaction vessel, sodium hydride (15 mg, 0.372 mmol) was suspended in N,N-dimethylformamide (4 ml) and ethylene glycol (23 mg, 0.372 mmol) was added thereto, followed by stirring at 80° C. for 30 minutes under an atmosphere of nitrogen gas. Subsequently, 5-(2-fluoro-4-pyridyl)-4,6-di(2-furyl)-2-pyrimidinamine (100 mg, 0.310 mmol) was added thereto, followed by stirring for 14 hours under the same conditions. Then, the reaction was terminated by adding water thereto. The reaction mixture was extracted with ethyl acetate, washed with water and brine, dried over anhydrous sodium sulfate and then the filtrate was concentrated. The resulting crude product was purified by silica gel column chromatography, to give the title compound (41 mg, 36%) as a pale yellow solid.

Procedure:
A solution of 6-acetoxy-7-methoxy-1,4-dihydroquinolin-4-one (6.2 g, 28 mmol) and thionyl chloride (75 ml) containing DMF (0.5 ml) was heated at reflux for 1 hour.

After cooling to room temperature, the solution was diluted with ethyl acetate and treated with aq sulfuric acid (50% v/v). The organic layer was separated and was washed successively with water, sulfuric acid, water, 1.25 M NaOH, water, and saturated aq NaCl. The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The resulting brown oil was purified via silica gel flash chromatography (5% ethyl acetate in heptane) to afford 1-bromo-4-fluoro-2-methoxy-5-methyl-benzene (17.1 g, 47%) as a clear liquid: Rf 0.70 (30% ethyl acetate in heptane); 1H NMR (CDCl3, 300 MHz) δ 7.34 (d, J=8.4 Hz, 1 H), 6.61 (d, J=10.8 Hz, 1 H), 3.85 (s, 3 H), 2.18 (d, J=1.8 Hz, 3 H); Anal. calcd for C8H8BrFO: C, 43.86; H, 3.68; Br, 36.48.

Procedure:
9.6 g of 5-bromo-1-hydroxyindane was dissolved in 100 ml of dry methylene chloride. To the solution were added, at room temperature, 570 mg of pyridinium p-toluenesulfonate and 4.5 ml of 3,4-dihydro-2H-pyran. The resulting mixture was stirred at the same temperature for 3 hours. The reaction mixture was added to ice water. The organic layer was separated, washed with a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure. The residue thus obtained was purified by column chromatography (eluant: toluene/ethyl acetate=15/1) to obtain 13.1 g of oily 5-bromo-1-(tetrahydropyran-2-yloxy)indane.

The suspension was heated to reflux for 1.5 h, allowed to cool to room temperature, and treated sequentially with 2-methoxy-4-methylbenzenesulfonamide (see Preparation 11, International Patent Application WO 97/43260; 3.0 kg) and 1,8-diazabicyclo[5.4.0]undec-7-ene (2.3 kg). The mixture was heated to reflux for 3.5 h, allowed to cool to room temperature and quenched by the addition of 2M hydrochloric acid (40 liters). The product was extracted from the acidic aqueous solution with dichloromethane (40 liters) and the organic phase was washed with 2M hydrochloric acid (40 liters) and water (40 liters). The organic phase was concentrated to low volume, diluted with acetonitrile (93 liters) and the resulting suspension heated to reflux. The mixture was allowed to cool and the precipitated product collected by filtration to give the subtitle compound as a white crystalline solid (5.34 kg, 71.3%).
