実験手順

HATU (0.149 g, 0.391 mmol) was added to a solution of (R)-2-(4-bromo-2-fluorophenyl)-2-((S)-1-(tert-butoxycarbonyl)-5,5-dimethylpyrrolidin-2-yl)acetic acid (0.168 g, 0.391 mmol; prepared analogously to that described in Example B), (5R,7R)-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol dihydrochloride (0.1 g, 0.326 mmol; see Example 3, Step 12), and N-ethyl-N-isopropylpropan-2-amine (0.171 mL, 0.977 mmol) in DCM (8 mL), and the reaction mixture was stirred overnight at room temperature. The reaction was then quenched with H2O. The reaction was washed with H2O (3×30 mL). The organic layer was dried with MgSO4, filtered and concentrated. Purification by flash chromatography yielded (S)-tert-butyl 5-((S)-1-(4-bromo-2-fluorophenyl)-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 (0.0334 g, 0.0517 mmol, 15.9% yield). LCMS (APCI+) 646.4, 648.5 m/z [M+H]+; Retention time=4.25 minutes.
