Procedure

HBTU (37 mg, 0.098 mmol) was added to a solution of (5R,7R)-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol dihydrochloride (30 mg, 0.098 mmol) and 3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)-2-hydroxypropanoic acid (35 mg, 0.098 mmol) in DCM (5 mL) and TEA (1 mL). The mixture was stirred at room temperature for 1 hour. The solvent was removed, and the residue was subject to column chromatography, eluted by DCM/MeOH (40:1). The resulting product was treated with HCl (4M, 2 mL) to afford 2-(4-chlorophenyl)-2-hydroxy-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(isopropylamino)propan-1-one as HCl salt (22 mg, 48%).
