0.09 g | Example 13 2-Amino-N-[(R)-carbamoylphenylmethyl]-N-[(R)-6-chloro-4-fluoroindan-1-yl]nicotinamide To a solution of (R)-6-chloro-4-fluoroindan-1-ylamine hydrochloride (0.1 g) in methanol (3 mL) were added triethylamine (0.046 g) and benzaldehyde (0.048 g), and the mixture was stirred for 0.5 hours at 65° C. The reaction mixture was allowed to cool to room temperature, and to the mixture were added <strong>[33225-72-8]2-nitronicotinic acid</strong> (0.083 g) and 4-phenylcyclohexen-1-ylisocyanide (0.083 g). The mixture was stirred overnight at 65° C., then allowed to cool to room temperature, and concentrated under reduced pressure. To the obtained residue were added tetrahydrofuran (4 mL), water (40 muL) and a solution of 4 mol/L hydrogen chloride in 1,4-dioxane (340 muL), and the mixture was stirred for 1 hour at room temperature. To the reaction mixture were added water and a saturated aqueous solution of sodium bicarbonate, and the crude product was extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: methanol/ethyl acetate/n-hexane=0/60/40 to 0/100/0 to 20/80/0) to afford 2-nitro-N-[(R)-carbamoylphenylmethyl]-N-[(R)-6-chloro-4-fluoroindan-1-yl]nicotinamide (0.090 g). A suspension of Raney catalyst was prepared as follows. A mixture of Raney (registered trademark) 2800 nickel slurry in water, active catalyst (Sigma-Aldrich) (200 muL) and ethanol was stirred, and the solvent was removed by decantation. The catalyst was washed 3 times with ethanol, and ethanol (1 mL) was added to form a suspension. | |
