Triethylamine → (7-benzo[b]thiophen-2-yl-1H-indazol-5-yl)-thiocarbamic acid S-methyl ester

Participants

Reaction Steps

To a solution of 7-benzo[b]thiophen-2-yl-1H-indazol-5-ylamine (Example #F.8.1, 530 mg, 2.0 mmol) and methyl chlorothioformate (0.25 mL, 2.8 mmol) in ethanol (10 mL) was added triethylamine (0.56 mL, 4.0 mmol). The reaction mixture was stirred at ambient temperature for about 16 hours and the resulting solid was collected by filtration, washed with water (3×50 mL), and dried to yield (7-benzo[b]thiophen-2-yl-1H-indazol-5-yl)-thiocarbamic acid S-methyl ester (448 mg, 66%); LC/MS (Table 1, Method e) Rt 2.14 min; m/z: [M−H]− 338.
