실험 절차

4M HCl/dioxane (2.27 mL, 9.09 mmol) was added to a solution of (R)-tert-butyl 4-(7,7-difluoro-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazine-1-carboxylate (0.092 g, 0.260 mmol) in dioxane (2 mL.) The reaction mixture was stirred at room temperature overnight, after which it was concentrated to dryness and dried on under high vacuum to give (R)-7,7-difluoro-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine dihydrochloride (0.079 g, 93.0% yield) as a solid.
