Triethylamine → HCID 17811098, compound

Participants

Reaction Steps

Triethylamine (0.18 ml) and 0.075 ml of methanesulfonyl chloride were added in that order under ice cooling to a solution of 134 mg of 7-aminomethylimidazo[5,1-b]thiazole in 2.5 ml of dry dichloromethane. In this state, the system was stirred for 2 hr while gradually raising the temperature to room temperature. The reaction solution was diluted with 20 ml of dichloromethane, followed by washing with saturated brine. The aqueous layer was extracted with 10 ml of dichloromethane. The organic layers were combined together, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed by distillation. The oil thus obtained was purified using Sephadex LH-20 (dichloromethane:methanol=1:1) to give 130 mg of 7-(methanesulfonylaminomethyl)imidazo[5,1-b]thiazole as a light yellow solid.
