Step 2. A mixture of 12 (100 mg, 0.40 mmol), 1 (67 mg, 0.40 mmol), potassium carbonate (55 mg, 0.40 mmol), Cul (3.8 mg, 0.019 mmol), and L-proline (2.3 mg, 0.019 mmol) in dioxane (4 mL) was stirred at 110¡ãC for 16 hours under an inert atmosphere. Upon completion, water (40 mL) was added and the reaction mixture was extracted with EtOAc (90 mL). The organic phase was washed with brine (50 mL) and concentrated under reduced pressure. Purification with prep-HPLC (0.075percent TFA/CH3CN/H20 system) resulted in Compound 121 (40 mg, 29percent) as yellow solid and TFA salt. 1H NMR (DMSO-d6, 400MHz) delta 8.69-8.68 (d, 1H), 8.53-8.52 (d, 1H), 7.99-7.94 (m, 3H), 7.77 (m, 1H), 7.67-7.62 (m, 3H), 7.07-7.05 (d, 1H), 6.83-6.81 (d, 1H), 4.95 (s, 2H); LCMS (ESI): m/z 340.1 (M+H).
936-16-3 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide 13638, aisothiazole compound, is more and more widely used in various fields.
