Reaction Steps

To a solution of 2-hydroxybenzothiazole (1.17 g, 7.58 mmol) in THF (10 mL) was added Et3N (1.1 mL, 7.89 mmol). A solution of 2-bromo-4′-methylacetophenone (1.67 g, 7.06 mmol) in THf (10 mL) was added dropwise. Another equivalent of Et3N was added after 24 hours. Purification by flash chromatography on silicagel (CH2Cl2) gave a white powder in 67% yield: mp 168-170° C.; 1H-NMR (DMSO-d6) 2.43 (s, 3H), 5.62 (s, 2H), 7.21 (t, 1H), 7.27 (d, 1H) 7.32 (t, 1H), 7.42 (d, 2H), 7.70 (d, 1H), 8.01 (d, 2H); Anal. (C16H13NO2S) C, H, N.
