To a solution of (4-benzothiazol-2-ylmethyl-phenyl)-methanol (2.1 g, 8.1 mmol) in CH2Cl2 (90 mL) was added thionyl chloride (0.65 mL, 8.9 mmol) and the mixture was stirred at rt for 4 h. The reaction mixture was concentrated to afford the title compound as a tan solid (2.6 g, 100%). MS (ESI): mass calcd. for C15H12ClNS, 273.04; m/z found, 274.0 [M+H]+. 1H NMR (500 MHz, CDCl3): 8.34 (d, J=8.2 Hz, 1H), 7.89 (d, J=8.2 Hz, 1H), 7.71-7.67 (m, 1H), 7.61-7.58 (m, 1H), 7.50-7.48 (m, 2H), 7.45-7.44 (m, 2H), 4.84 (s, 2H), 4.60 (s, 2H).
