Procedure

To a solution of oxalyl chloride (1.2 mL, 14.1 mmol) in 110 mL of methylene chloride at −78° C. is added DMSO (2.2 mL, 30.6 mmol) dropwiese. The reaction is stirred for 20 min. and {1-[1-(2-Hydroxy-1,1-dimethyl-ethyl)-1H-imidazol-4-ylcarbamoyl]-butyl}-carbamic acid tert-butyl ester (4.2g, 11.8 mmol) is added in 10 mL of methylene chloride. The reaction is stirred for 1 h, triethylamine (8.2 mL, 58.9 mmol) is added, and the reaction warmed to 0° C. for 20 min. The reaction is quenched with 100 mL of sodium bicarbonate, extracted with methylene chloride, dried, and concentrated to afford the title compound (4.5 g): MS m/z 353.2 (M+1).
