Procedure

[(2-tert-Butyl-1,1-dioxido-3-oxo-5-phenyl-2,3-dihydroisothiazol-4-yl)amino]acetic acid (100 mg, 0.30 mmol), (4-methoxyphenyl)methanol (204 mg, 1.48 mmol), TEA (123 μL) and DMAP (9 mg, 0.074 mmol) were dissolved in DCM (10 mL). DMF 81 mL) and EDC (113 mg, 0.59 mmol) was added and the solution was stirred at 40° C. over night. Aqueous K2CO3 (1M, 50 mL) was added and the reaction mixture was extracted with DCM. The organic phases were combined, dried over MgSO4, filtered and evaporated. The residue was purified by preparative HPLC affording the title compound (23 mg, 17%). 1H NMR (CDCl3, 400 MHz) δ 1.69 (s, 9H), 3.54 (s, 2H), 3.77 (s, 3H), 4.98 (s, 2H), 5.79 (t, 1H), 6.83 (d, 2H), 7.17 (d, 2H), 7.32-7.40 (m, 5H). 13C NMR (CDCl3, 100 MHz) δ 27.7, 45.4, 55.5, 61.8, 67.6, 109.6, 114.2, 124.4, 127.0, 128.9, 130.1, 130.7, 131.5, 134.8, 159.2, 160.2, 168.7.
