Reaction Steps

Using the same procedureas for Example 179, 2-t-butyl 3-ethyl 6-(3-t-butyl-5-(3-(3-(pyridin-3-yloxy)phenyl)ureido)-1H-pyrazol-1-yl)-3,4-dihydroisoquinoline-2,3(1H)-dicarboxylate (0.029 g, 0.044 mmol), available from experimental 184) in 3N hydrochloric acid in MeOH (10.0 mL) was stirred at RT for 1 h. The solvent was evaporated and the residue was dissolved in 3-amino-1,2-dihydroxypropane (0.200 g, 2.2 mmol) in MeOH (0.5 mL) and the solution was stirred at RT for 2 d. The solvent was evaporated and the residue was purified by reverse phase chromatography and coevaporated with THF/4N HCl to yield 1-(1-(1-((2,3-dihydroxypropyl)carbamoyl)-1,2,3,4-tetrahydroisoquinolin-6-yl)-3-t-butyl-1H-pyrazol-5-yl)-3-(3-(pyridin-3-yloxy)phenyl)urea (24 mg, 81% yield) as a pale yellow solid. 1H-NMR (MeOH-d4): δ 8.68 (d, 1H, J=3.2 Hz), 8.60 (d, 1H, J=7.6 Hz), 8.23 (ddd, 1H, J=8.8, 2.6, 1.0 Hz), 8.06 (dd, 1H, J=8.4, 1.4 Hz), 7.70 (dd, 1H, J=−9.0, 1.8 Hz), 7.58-7.54 (m, 3H), 7.42 (t, 1H, J=8.0 Hz), 7.22 (dt, 1H, J=8.4, 1.0 Hz), 6.90 (dd, 1H, J=6.8, 1.6 Hz), 6.58 (d, 1H, J=1.2 Hz), 5.29 (s, 1H), 3.84-3.63 (m, 2H), 3.63-3.51 (m, 5H), 3.30-2.87 (m, 2H), 1.37 (s, 9H), urea, amine, hydroxy and amide protons not visible. MS expected 600.3 found 600.2.
