Versuchsvorschrift

To a chloroform (1 mL) solution of Compound 49 (78 mg), 6N HCl (1 mL) was added and the mixture was stirred at room temperature for 1 hour. While the reaction mixture was cooled with ice, a 4N aqueous sodium hydroxide solution was added to neutralize the mixture. The resulting product was extracted with chloroform and the organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The resulting residue was purified by amino-coated silica gel (Fuji Sylysia Chemical Ltd.; NH-DM1020) column chromatography (ethyl acetate) to give 37.5 mg (62% yield) of 2-(5-amino-4,6-dimethylpyrimidine-2-yloxy)-N-(1-(cyclopropylmethyl)piperidine-4-yl)-N-methylacetamide. Then, to a methanol solution of 2-(5-amino-4,6-dimethylpyrimidine-2-yloxy)-N-(1-(cyclopropylmethyl)piperidine-4-yl)-N-methylacetamide, 2 equivalents of 4N HCl/1,4-dioxane solution was added and the mixture was concentrated under reduced pressure. The desired product was afforded by recrystallization from methanol/ethyl acetate as white crystals.
