The 3-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-6-(2-(2,4-difluorophenyl)-6,7-dihydro-5H-pyrrolo[1,2-a]imidazol-3-yl)-[1,2,4]triazolo[4,3-b]pyridazine (0.606 g, 1.16 mmol, Preparation #E.1.1.1) was dissolved in THF (15 mL) and reacted at about ambient temperature with TBAF (1.0 M in THF, 1.39 mL, 1.39 mmol) for about 4 h. The crude reaction mixture was partitioned between water and DCM. The organics were dried over MgSO4, filtered and concentrated under reduced pressure. The resulting crude material was purified by chromatography on silica gel (DCM/MeOH gradient from 100:0-85:15) and triturated with a mixture of heptane/Et2O (90:10) to give the title compound as a yellow solid (0.074 g, 16%): LC/MS (Table 1, Method g) Rt=1.64 min.; MS m/z: 411.98 (M+H)+.
