Procedure

N-Bromosuccinimide (0.763 g, 4.29 mmol) was added to a solution of 2-propen-1-yl {3-[(2-chloro-4-pyrimidinyl)acetyl]-2-fluorophenyl}carbamate (1.5 g, 4.29 mmol) in dichloromethane (DCM) (50 mL). After 1 h of stirring, 1,1-dimethylethyl (2-amino-1,1-dimethyl-2-thioxoethyl)carbamate (0.936 g, 4.29 mmol) was added to the reaction mixture and heated to 80° C. for 2 h. The reaction mixture was diluted with 150 cc of EtOAc and washed with water (5×100 cc). The EtOAc layer was dried over MgSO4 and filtered and concentrated in vacuo. The residue was purified via chromatography on silica gel using Hex to 25% EtOAc in Hex to obtain the title compound (1.28 g, 54% yield). MS (ESI): 548.3 [M+H]+
