실험 절차

A reaction mixture of (1R,5R)-benzyl 3-(5-(4-(6-(2-((1R,3S,5R)-2-(tert-butoxycarbonyl)-2-azabicyclo[3.1.0]hexan-3-yl)-1H-imidazol-5-yl)naphthalen-2-yl)phenyl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (0.305 g, 0.416 mmol) and NaHCO2 (0.070 g, 0.832 mmol) in MeOH (15 mL) was charged with 10% Pd/C (0.022 g, 0.021 mmol). The resulting suspension was vacuum flushed with N2 (3×) and placed under 1 atm of H2 (balloon) for 3 h at room temperature. The mixture was then filtered though a pad of diatomaceous earth (CELITE®) and concentrated under vacuum. An off-white solid corresponding to (1R,3S,5R)-tert-butyl 3-(5-(6-(4-(2-((1R,5R)-2-azabicyclo[3.1.0]hexan-3-yl)-1H-imidazol-5-yl)phenyl)naphthalen-2-yl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (0.235 g) was recovered and used without further purification.
