Hexane → N-(4-methoxyphenyl)-4-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine-1-carboxamide

Participants

Reaction Steps

To a solution of 1-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine (200 mg, 0.812 mmol) and triethylamine (0.113 ml, 0.812 mmol) in tetrahydrofuran (2 ml) was added 4-methoxyphenyl isocyanate (0.158 ml, 1.22 mmol), and the mixture was stirred at room temperature for 2 hours. To the resulting solution was added hexane (4 ml) and the solid was separated by filtration, which was recrystallized from a mixed solvent of tetrahydrofuran and ethyl acetate to give 180 mg (56.1%) of the desired product as a solid.
