Procedure

The above mentioned tert-butyl (S)-1-(5-(3-fluoro-4-nitrophenyl)-1,3,4-thiadiazol-2-yl-boc-amino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate was dissolved in 20 mL 2M THF solution of methanamine (20 mL, 40 mmol) in a microwave heating tube. The tube was heated at 120° C. for 10 minutes. The THF solution was mixed with 200 mL EtOAc. The organic phase was washed with water, twice with saturated aqueous ammonium sulfate twice, and dried over sodium sulfate. After removing the solvent, the product was used directly in the next step.
