Reaction Steps

The suspension of 5-(2-benzyl-2H-indazol-6-yl)-7-piperidin-4-ylpyrrolo[2,1-f][1,2,4]triazin-4-amine (500 mg, 1.81 mmol) was treated with N,N-diisopropylethylamine (411 uL, 2.36 mmol) followed by 2-chloro-N,N-dimethylacetamide (192 uL, 1.42 mmol). The mixture was heated at 60° C. for 3 h then cooled to rt. The white solid was filtered then purified by ISCO® using 0-10% 2N NH3 in MeOH/EtOAc. 313 mg (52.1%) of the desired product was isolated. 1H NMR (400 MHz, CD2Cl2) δ 8.42 (s, 1H), 8.04 (s, 1H), 8.19-8.12 (m, 2H), 7.82-7.70 (m, 5H), 7.62-7.60 (d, 1H), 6.99 (s, 1H), 6.02 (s, 2H), 5.96 (s, 2H), 3.70-3.59 (m, 3H), 3.50 (s, 3H), 3.48-3.40 (m, 2H), 3.36 (s, 3H), 2.79-2.50 (m, 2H), 2.59-2.48 (m, 2H), 2.36-2.24 (m, 2H); LC-MS m/z[M+H]+ 509.2, RT 2.09 min.
