Procedure

(5R,7R)-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol dihydrochloride (0.0661 g, 0.215 mmol), HATU (0.0744 g, 0.196 mmol), and DIEA (d 0.742; 0.0341 mL, 0.196 mmol) were added to a solution of (S)-2-((S)-1-(tert-butoxycarbonyl)-5,5-dimethylpyrrolidin-2-yl)-2-(3-chlorophenyl)acetic acid (0.072 g, 0.196 mmol, see Example B, Step 3) in DCM (25 mL). The reaction was stirred overnight at room temperature. The reaction was partitioned between water (20 mL) and DCM (50 mL), and the layers were separated. The organics were washed with water (2×10 mL). The aqueous portion was back extracted with DCM (25 mL), dried (MgSO4), concentrated to an oil and purified by flash chromatography (5% MeOH/DCM) to give (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 (0.090 g, 0.154 mmol, 78.7% yield). LC/MS=3.79 minutes, (APCI+) m/z=584 [M+H]+.
