Procedure

2-[5-(4-Bromonaphthalen-1-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carboxylic acid tert-butyl ester (3.80 g), 2-methoxycarbonylamino-3-methyl-butyric acid (2.57 g), and HATU (5.88 g) were dissolved in anhydrous DMF (85 mL), and N-methylmorpholine (2.86 mL) was added. The reaction mixture was stirred at ambient temperature for 22 hours and evaporated under vacuum. The oil was dissolved in dichloromethane, purified by chromatography (0-50% ethyl acetate:hexanes), and evaporated under vacuum, giving (1-{2-[5-(4-bromonaphthalen-1-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester (6.10 g, crude) as a tan solid.
