Participants

Reaction Steps

To a stirred solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(octahydropyrazino[2,1-c][1,4]oxazin-3-yl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (50 mg, 0.10 mmol), triethylamine (43 μL, 0.31 mmol), and glycolic acid (8 mg, 0.10 mmol) in DMF (1 mL), benzotriazol-1-yloxytris(dimethylamino)-phosphonium hexafluorophosphate (51 mg, 0.11 mmol) was added at 0° C. The reaction was allowed to stir for 30 minutes while warming to rt. The mixture was partitioned between ethyl acetate (30 mL) and saturated aqueous K2CO3 solution (10 mL). The layers were separated and the organic phase was washed, dried (Na2SO4), and concentrated to dryness. The residue was triturated with Et2O to obtain 20 mg (36%) of the desired product. 1H-NMR (DMSO-d6) 8.53 (s, 1H), 7.91 (s, 1H), 7.78 (d, 1H), 7.57 (s, 1H), 7.35 to 7.27 (m, 5H), 7.11 (dd, 1H), 6.71 (s, 1H), 5.64 (s, 2H), 5.16-5.12 (m, 1H), 4.35-3.96 (m, 3H), 3.88-3.85 (m, 1H), 3.67-3.55 (m, 1H), 3.36-3.27 (m, 1H), 3.12-3.01 (m, 1H), 2.79-2.64 (m, 2H), 2.55-2.41 (m, 3H), 2.19-2.10 (m, 2H); LC-MS [M+H]+=539, RT=2.19 min.
