To a solution of 5-(5-phenyl-4-((pyridin-2-ylmethyl)amino)pyrrolo[2,1-f][1,2,4]triazin-2-yl)nicotinonitrile (45.0 mg, 0.112 mmol) in t-butanol (5.00 mL, 502 mmol) was added potassium tert-butoxide (125 mg, 1.12 mmol) and the contents were heated to 90° C. for 12 h. The reaction mixture was allowed to cool and the solvents were removed under reduced pressure. The residue was dissolved in CH2Cl2 (25 mL) and washed with 1.5 N HCl (20 mL). The organic layer was separated and dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give a brown solid. The solid was purified by preparative HPLC (Condition B-64 as described in general methods) to give 5-(5-phenyl-4-((pyridin-2-ylmethyl)amino)pyrrolo[2,1-f][1,2,4]triazin-2-yl)nicotinamide (21.0 mg, 44.7%) as a brown solid. LCMS Condition B-12: retention time 2.07 min, [M+1]=422.2. HPLC Condition B-1: retention time=6.85 min, Purity=96.30%. 1H NMR (400 MHz, DMSO-d6) δ ppm 4.96 (d, J=4.4 Hz, 2H), 6.84 (d, J=2.8 Hz, 1H), 7.25-7.53 (m, 8H), 7.58-7.72 (m, 3H), 7.93 (d, J=2.8 Hz, 1H), 8.31 (s, 1H), 8.92 (s, 1H), 9.12 (s, 1H), 9.51 (s, 1H).
