Procedure

Into a 50 ml round bottomed flask were added 6-[(2-methylpropyl)amino]-1,3-benzothiazole-2-thiol (100 mg, 0.42 mmol), acetone (10 ml), N,N-diisopropylethylamine (54.2 mg, 0.42 mmol) and 4-chlorophenyl chloroformate (78.8 mg, o.42 mmol). The reaction mixture was stirred for 10 h, filtered, and the solid that was obtained was triturated with diethyl ether to afford 38 mg (48%) of the title compound. 1H NMR (DMSO-d6) δ=0.85 (d, 6H), 1.70 (m, 1H), 3.53 (br s, 2H), 7.12 (d, 2H), 7.31 (d, 1H), 7.41 (m, 3H), 7.79 (s, 1H); ESIMS: m/z 393 (M+H).
