Procedure
To a 250 mL round bottom flask was added (R)-1-(4-(4-iodophenyl)-1-methyl-1H-imidazol-2-yl)-N-methylethanamine (3.1 g, 9.1 mmol), methyl chloroformate (0.84 mL, 10.9 mmol), Na2CO3 (1.15 g, 10.9 mmol), and THF (100 mL). The reaction was stirred for 2 hours, followed by the addition of EtOAc (50 mL) and water (10 mL). The organic layer was dried over Na2SO4, filtered, and concentrated to give 1.50 g (41%) of (R)-methyl 1-(4-(4-iodophenyl)-1-methyl-1H-imidazol-2-yl)ethyl(methyl)carbamate as an off-white solid (M+H (m/z)=400).
