実験手順

To a solution of 1-carboxymethyl-3-methoxymethyl-pyrrolidine-3-carboxylic acid methyl ester (compound 97) (0.21 mmol), 2-(4-piperazin-1-yl-phenyl)-pyrimidine (compound 10, see Example 1 Step 7) (0.21 mmol), O-(7-azabenzotriazol-1-yl-)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (78 mg, 0.21 mmol) in dry DMF (2 ml) was added N,N-diisopropylethylamine (108 μl, 0.62 mmol). The reaction mixture was stirred for 4 hours, and evaporated to a residue that was partitioned in ethyl acetate and saturated sodium carbonate. Organic layer was isolated, washed with water, brine and dried over magnesium sulfate. Evaporation of solvent provided a crude product which was chromatographed with 5% methanol in dichloromethane to furnish the title compound (97 mg).
