実験手順

(5R,7R)-4-(4-((S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoyl)-1,4-diazepan-1-yl)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-yl 4-nitrobenzoate (50 mg, 0.069 mmol) was dissolved in a THF/water mixture (1:1, 2 mL), and then solid lithium hydroxide (6 mg, 0.139 mmol) was added. The resultant mixture was stirred at ambient for 16 hours, at which time it was diluted with EtOAc and then washed twice with saturated sodium bicarbonate solution. The organic layer was dried over magnesium sulfate, filtered and concentrated. The resulting residue was taken up in dichloromethane (5 mL), and then HCl (4M in dioxane, 0.25 mL) was added. The mixture was stirred for 16 hours, at which time solvents were removed via rotary evaporation. The resulting residue was dissolved in dichloromethane (1 mL) and then added to diethyl ether (50 mL). The resulting precipitate was collected by filtration and dried to give (S)-2-(4-chlorophenyl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)-1,4-diazepan-1-yl)-3-(isopropylamino)propan-1-one dihydrochloride (29 mg, 78%). LCMS (APCI+) M+=472.2, Rt=2.05 min.
