Reaction Steps

A solution of tert-butyl N-[[4-[5-[3-[bis(tert-butoxycarbonyl)amino]-6-[(1R,5S)-6-(dimethylcarbamoyl)-3-azabicyclo[3.1.0]hexan-3-yl]pyrazin-2-yl]-1,3,4-oxadiazol-2-yl]phenyl]methyl]-N-methyl-carbamate (75 mg, 0.1 mmol) in 0.8 mL of 50% TFA-DCM mixture was stirred under an atmosphere of nitrogen at room temperature for 1 h. The solvents were evaporated and the crude material was purified via reverse phase HPLC using 10 to 99% methanol in water (TFA modifier) to obtain (1R,5S)-3-[5-amino-6-[5-[4-(methylaminomethyl)phenyl]-1,3,4-oxadiazol-2-yl]pyrazin-2-yl]-N,N-dimethyl-3-azabicyclo[3.1.0]hexane-6-carboxamide. 1H NMR (400 MHz, DMSO-d6) δ 8.87 (s, 2H), 8.16 (d, J=8.2 Hz, 2H), 7.91 (s, 1H), 7.73 (d, J=8.2 Hz, 2H), 6.76 (s, 2H), 4.26 (t, J=5.7 Hz, 2H), 3.86 (d, J=10.2 Hz, 2H), 3.49-3.46 (m, 2H), 3.10 (s, 3H), 2.84 (s, 3H), 2.63 (t, J=5.2 Hz, 3H), 2.09 (s, 2H), 1.90 (t, J=3.1 Hz, 1H). LC/MS m/z 435.2 [M+H]+.
