Procedure
tert-Butyl [4-(2-{2-amino-5-[4-(methylsulfonyl)benzyl]-1,3-thiazol-4-yl}ethyl)phenyl]carbamate (140 mg) was dissolved in pyridine (2 ml) under N2 atmosphere. Then, ethyl chloroformate (30.2 ml) was added to the solution at 0° C. The reaction mixture was stirred at r.t. for 2 hours, and concentrated in vacuo. The residue was dissolved in AcOEt, and washed with 1N-HCl, water and brine. The organic layer was dried over anhydrous MgSO4, and concentrated in vacuo to give ethyl {4-(2-{4-[(tert-butoxycarbonyl)amino]phenyl}ethyl)-5-[4-(methylsulfonyl)benzyl]-1,3-thiazol-2-yl}carbamate (155.8 mg) as an off-white amorphous substance.
