Reaction Steps

4M HCl in dioxane (6 mL, 24 mmol) was added to a solution of (S)-tert-butyl 5-((S)-1-(3-chlorophenyl)-2-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-2-oxoethyl)-2,2-dimethylpyrrolidine-1-carboxylate (0.020 g, 0.034 mmol) in dry DCM (15 mL) and stirred overnight. The solvent was evaporated to dryness to reveal (S)-2-(3-chlorophenyl)-2-((S)-5,5-dimethylpyrrolidin-2-yl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)ethanone dihydrochloride (0.015 g, 0.027 mmol, 79% yield). HPLC, 220 nm, retention time=1.91 minutes, 92% purity. LC/MS, retention time=2.15 minutes, (APCI+) m/z=484 [M+H]+. 1H NMR (400 MHz, D2O) 8.35 (s, 1H), 7.35-7.28 (m, 3H), 7.25-7.15 (m, 1H), 5.22 (t, J=8.20 Hz, 1H), 4.28-4.00 (m, 2H), 3.88-3.71 (m, 1H), 3.67-3.55 (m, 1H), 3.55-3.42 (m, 4H), 3.36-3.05 (m, 1H), 2.16 (dd, J1=7.81 Hz, J2=13.27 Hz, 1H), 2.10-1.93 (m, 1H), 1.88-1.70 (m, 4H), 1.36 (s, 3H), 1.30 (s, 3H), 0.94 (d, J=7.03 Hz, 3H).
