Pyridine → 2-({[6-Butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carbonyl]-amino}-methyl)-morpholine-4-carboxylic acid tert-butyl ester

Participants

Reaction Steps

To a solution of 6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carboxylic acid pentafluorophenyl ester hydrochloride (0.18 mmol, 0.1 g, Example 90) and 0.1 mL of pyridine in 2 mL of THF was added 2-aminomethyl-morpholine-4-carboxylic acid tert-butyl ester (0.4 mmol, 0.09 g). The mixture was shaken at room temperature, and upon completion of the reaction, the solvent was removed. The residue was chromatographed with 4% methanolic solution of ammonia (2.0 M ammonia in methanol) in EtOAc to provide 2-({[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carbonyl]-amino}-methyl)-morpholine-4-carboxylic acid tert-butyl ester. LCMS: m/z 553.0 [M+1].
