Procedure

To a solution of 5-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-cyclohexyloxy-benzoic acid (0.203 mmol, 94.9 mg), HBTU (0.203 mmol, 79.3 mg), diisopropyl ethyl amine (0.34 mmol, 0.0592 mL) in DMF (1 mL) was added 2-amino-2-methyl-propan-1-ol (0.45 mmol, 42.2 mg). It was stirred at room temperature for 20 min. The reaction mixture was partitioned between ethyl acetate (12 mL) and saturated aq. sodium bicarbonate solution (12 mL). The ethyl acetate layer was washed again with saturated aq. sodium bicarbonate solution (2×12 mL) and dried over sodium sulfate. The organic solvents were removed in vacuo to give 5-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-cyclohexyloxy-N-(2-hydroxy-1,1-dimethyl-ethyl)-benzamide (87.7 mg).
