Reaction Steps

To 150 mg (0.355 mmol) of 4-(6-butylamino-imidazo[1,2-b]pyridazin-3-yl)-N-(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-benzamide was added 15 ml of AcOH and 5 mL of water and heated to 60° C. for 1.5 hr. It was concentrated and the crude was purified on the acetic PREP HPLC to yield 107 mg (79%) of the titled compound. 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.00 (t, J=7.39 Hz, 3H) 1.42-1.55 (m, 2H) 1.66-1.76 (m, 2H) 3.40 (t, J=7.17 Hz, 2H) 3.43-3.52 (m, 1H) 3.56-3.65 (m, 3H) 3.84-3.93 (m, 1H) 7.24 (d, J=9.92 Hz, 1H) 7.96 (d, J=9.92 Hz, 1H) 8.00-8.05 (m, 2H) 8.23-8.28 (m, 2H) 8.30 (s, 1H); LRMS (ESI) m/e 384.0 [(M+H)+, calcd for C20H25N5O3 383.0]
