Participants

Reaction Steps

To a mixture of 4-(4-chlorobenzyl)-2-(pyridin-4-yl)thiazole-5-carboximidamide hydrochloride (112 mg, 0.306 mmol) in DMF (2.96 mL) was added sodium carbonate (162 mg, 1.53 mmol) and 2-(3-bromo-2-oxopropyl)isoindoline-1,3-dione (95.0 mg, 0.337 mmol) and the resulting mixture was heated at 100 degrees for 4 hours. The reaction was cooled and taken up in ethyl acetate (30 mL) and water (5 mL). The layers were separated and the organic layer was washed with water (3×5 mL). The organic layer was dried, filtered and concentrated in vacuo. The residue was purified by silica gel chromatography (MeOH/DCM=0/100→10/90) to give 47 mg (30% yield) of the title compound. LC/MS (FA) ES+ 512. 514. 1H NMR (300 MHz, DMSO-d6) δ: 12.67 (bs, 1H), 8.69-8.67 (m, 2H), 7.91-7.79 (m, 6H), 7.27-7.24 (m, 3H), 7.11-7.08 (m, 2H), 4.77 (s, 2H), 4.45 (s, 2H).
