Reaction Steps
A mixture of tert-butyl 3,3-difluorocyclopentylcarbamate and DCM/TFA (50%, 7 mL) was stirred at 25° C. for 30 min. The reaction mixture was concentrated down and dried in vacuo to afford the title compound as an orange semi-solid, TFA salt (0.51 g, 99%). 1H NMR (400 MHz, DMSO-d6) δ 1.69-1.88 (m, 1 H) 2.00-2.22 (m, 3 H) 2.22-2.38 (m, 1 H) 2.56 (d, J=6.32 Hz, 1 H) 3.71 (d, J=5.31 Hz, 1 H) 8.20 (br. s., 3 H).
