Reaction Steps

5-(2-Benzyl-2H-indazol-6-yl)-7-(1,2,3,4-tetrahydro-isoquinolin-7-ylmethyl)-pyrrolo[2,1-f][1,2,4]triazin-4-ylamine (0.100 g, 0.21 mmol) was dissolved in MeOH (1 mL) and (1-ethoxy-cyclopropoxy)-trimethyl-silane (0.22 g, 1.24 mmol) was added followed by acetic acid (0.118 mL, 2.05 mmol) and sodium cyanoborohydride (0.058 g, 0.92 mmol). The resulting mixture was refluxed overnight and then allowed to cool. The mixture was filtered, concentrated and the residue was purified by preparative HPLC to give 55 mg (50%) of the title compound. 1H-NMR (CD3OD-d4) 8.36-8.23 (m, 1 H), 7.81 (s, 1 H), 7.78 (dd, 1H), 7.38-7.29 (m, 4 H), 7.19 (dd, 1 H), 7.10-6.99 (m, 2 H), 6.44 (s, 1 H), 5.63 (s, 2 H), 4.23 (s, 2 H), 3.72 (s, 2 H), 2.96-2.81 (m, 4 H), 1.86-1.79 (m, 1 H), 0.57-0.75 (m, 4 H); LC-MS [M+H]+=426.3, RT=2.32 min.
