실험 절차

In a 50 mL pear flask was added (S)-4-(1,2-dihydroxypropan-2-yl)-N-(1-ethyl-1H-pyrrolo[3,2-c]pyridin-6-yl)benzamide (92 mg, 0.27 mmol) in DMF (2 ml) to give a solution. At room temperature 1-chloropyrrolidine-2,5-dione (36 mg, 0.27 mmol) was added, and the mixture was heated to 60° C. for 4 hours, at which point the reaction seemed to have stalled. An additional 0.2 equivalence of 1-chloropyrrolidine-2,5-dione was added, and the mixture was heated to 60° C. for another hour. The mixture was then cooled, and partitioned between brine and EtOAc. The aqueous layer was further extracted with EtOAc, and the organic layers were combined, washed with brine, dried, filtered and concentrated in vacuo. The residue was then triturated with hot EtOAc, and the resulting precipitate was collected on a fritted-glass funnel. The collected solid was then recrystallized from EtOH to give the product (S)—N-(3-chloro-1-ethyl-1H-pyrrolo[3,2-c]pyridin-6-yl)-4-(1,2-dihydroxypropan-2-yl)benzamide (23 mg, 0.062 mmol, 22% yield) as a pink solid. 1H NMR (DMSO-d6) δ 10.68 (s, 1H), 8.60 (s, 1H), 8.37 (s, 1H), 8.02 (s, 2H), 7.69 (s, 1H), 7.59 (s, 2H), 5.05 (s, 1H), 4.76 (t, J=5.8 Hz, 1H), 4.19 (q, J=7.1 Hz, 2H), 3.40-3.50 (m, 2H), 1.34-1.45 (m, 6H); m.p. 223.0-223.9° C.
