실험 절차

To a mixture of 6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carboxylic acid (Example 93, 0.34 mmol, 0.12 g), HBTU (0.34 mmol, 0.13 g) and (S)-5-aminomethyl-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (0.34 mmol, 0.05 mL) in DMF was added DIEA (1.0 mmol, 0.17 mL). Upon completion of the reaction, the mixture was diluted with ether, and then poured into water. The resulting mixture was extracted, the organic layer was dried. The solvent was removed, and the resulting residue was chromatographed with 4:1 hexane/EtOAc to provide (S)-5-({[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carbonyl]-amino}-methyl)-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester was used as is in the next step. LCMS: m/z 566.9 [M+1].
