With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; N-ethyl-N,N-diisopropylamine; In tetrahydrofuran; at 20℃; for 18.0h;Product distribution / selectivity; | tert-Butyl(3S,8aR)-3-[(1R)-1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl]hexahydropyrrolo[1,2-a]pyrazine-2(1H)-carboxylate (380 mg) obtained in Example 5 (ii) was dissolved in 4M hydrogen chloride-ethyl acetate solution (5 mL), and the solution was stirred at room temperature for 18 hr. The precipitate resulting from the reaction mixture was collected by filtration. To the collected precipitate were added tetrahydrofuran (5 mL), N-ethyl-N-(1-methylethyl)propan-2-amine (0.497 mL), <strong>[1098184-12-3](2S)-[(benzyloxy)carbonyl]amino}(tetrahydro-2H-pyran-4-yl)ethanoic acid</strong> (418 mg) and 1-hydroxybenzotriazole (218 mg). To this mixture was added 1-ethyl-3-3-dimethylaminopropyl)carbodiimide hydrochloride (310 mg), and the mixture was stirred at room temperature for 18 hr. To the reaction mixture was added water (50 mL), and the mixture was extracted with ethyl acetate (200 mL). The organic layer was washed with saturated brine (50 mL), dried over anhydrous magnesium sulfate, and filtered, and the filtrate was concentrated to give an oil. This oil (500 mg) was dissolved in methanol (3 mL), 20% palladium-carbon (100 mg, 20 wt %) was added thereto, and the mixture was stirred at room temperature for 4 hr under a hydrogen atmosphere (3 atm). The insoluble material was filtered off through a celite pad, and the filtrate was concentrated to give an oil. |

The mixture was diluted with ethyl acetate (30 mL), and washed with water (30 mL), saturated aqueous sodium hydrogen carbonate solution (50 mL) and saturated brine (50 mL). The organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=15/85?100/0) to give the title compound (200 mg) as a colorless amorphous powder. LC-MS: 577 (MH+) |
