실험 절차
4M HCl/dioxane (0.860 ml, 3.44 mmol) was added to a solution of tert-butyl (S)-2-(4-chlorophenyl)-3-(4-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-oxopropylcarbamate (0.043 g, 0.0860 mmol) in dioxane (1.2 mL). The reaction mixture was stirred at room temperature overnight (16 hours), after which it was concentrated and dried on high vacuum line. The resulting residue was dissolved in minimal MeOH, and the product was triturated by the addition of ether. The resulting solids were isolated by filtration through Varian quantitative membrane filter paper with nitrogen pressure, rinsed with ether, dried with nitrogen pressure, and further dried in vacuo to give (S)-3-amino-2-(4-chlorophenyl)-1-(4-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)propan-1-one dihydrochloride (0.032 g, 78.7% yield) as a white powder. LC/MS (APCI+) m/z 400 [M+H]+.
