The title compound was prepared in an analogous manner to 2-amino-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid [3-(5-chloro-2-difluoromethoxy-phenyl)-1-piperidin-4-yl-1H-pyrazol-4-yl]-amide using tert-butyl (3-((3-(5-chloro-2-(difluoromethoxy)phenyl)-1H-pyrazol-4-yl)carbamoyl)pyrazolo[1,5-a]pyrimidin-2-yl) carbamate and trans-toluene-4-sulfonic acid 3-tert-butoxycarbonylamino-cyclobutyl ester to afford the title compound as a white solid. LCMS (Method 5) [M+H]+=489.1, RT=2.87 min. 1H NMR (400 MHz, DMSO-d6) δ: (ppm) 9.53 (s, 1H), 8.93 (dd, 1H, J=1.6, 6.8 Hz), 8.37-8.34 (m, 2H), 7.63-7.60 (m, 2H), 7.45 (d, 1H, J=7.2 Hz), 7.25 (t, 1H, J=72.6 Hz), 7.00 (dd, 1H, J=4.5, 6.5 Hz), 6.56 (s, 2H), 4.51-4.41 (m, 1H), 3.18-3.07 (m, 1H), 2.75-2.67 (m, 2H), 2.24-2.14 (m, 2H).
