Procedure

N-(2-Aminoacetyl)-4-(2-butyl-4-chloro-5-formyl-imidazol-1-ylmethyl)benzenesulfonamide (770 mg, 1.2 mmol, 1.0 eq) and 2-(2,2-Dimethylpropionyloxycarbamoyl)-4-methylpentanoic acid (360 mg, 1.2 mmol, 1.0 eq) were dissolved in 13 mL DMF. HATU (460 mg, 1.2 mmol, 1.0 eq) was then added followed by DIPEA (630 μL, 3.6 mmol, 3.0 eq) and the mixture was stirred at room temperature. After 3 hours, the mixture was diluted with 30 mL EtOAc, washed with 20 mL 10% aq. LiCl solution, water, saturated aqueous NaCl, dried over MgSO4, filtered, and concentrated under reduced pressure to yield crude intermediate 3a. MS m/z: [M+H+] calcd for C29H40ClN5O8S, 654.2. found 654.4.
