Participants

Reaction Steps

To an ice cold solution of 4-(2-amino-6-phenoxy-quinoline-3-yl)-4-(S)-cyclohexyl-butyric acid (0.085 mg, 0.19 mmol) in dichloromethane (2.0 mL) was added isobutyl chloroformate (0.025 mL, 0.19 mmol) and N-methylmorpholine (0.021 mL, 0.019 mmol). The reaction mixture was stirred at this temperature for 0.5 h. The reaction mixture was then reacted with a solution of (3,3-dimethyl-butyl)-(1-methyl-1H-imidazole-2-ylmethyl)-amine (0.037 mg, 0.19 mmol) in dichloromethane (0.5 mL) and stirred at 0° C. for 0.5 h. To this reaction mixture was added CHCl3, and the resulting mixture washed with H2O and saturated aqueous NaHCO3 solution. The organic layer was dried (MgSO4) and concentrated in vacuo to yield crude material. The crude material was purified by silica gel column chromatography using 4% MeOH in CHCl3 to yield 4-(2-amino-6-phenoxy-quinolin-3-yl)-4-(S)-cyclohexyl-N-(3,3-dimethyl-butyl)-N-(1-methyl-1H-imidazol-2-ylmethyl)-butyramide as a solid.
