Methyl iodide → HCID 15457460, compound

Participants

Reaction Steps

A solution of 900 mg of crude 2-methyl-4-(2-phenoxyphenyl)-5-thioxo-1,2,4-triazolidin-3-one in 50 mL of tetrahydrofuran was treated with 150 mg of sodium hydride (60% oil dispersion). After 5 minutes, 0.5 mL of iodomethane was added, and the mixture was stirred at ambient temperature overnight. The solid was removed by filtration and the filtrate concentrated to an oil. The oil was partitioned between ether and 1N hydrochloric acid solution. The organic phases were dried (MgSO4), filtered and concentrated under reduced pressure. The residue was triturated in hexane/n-butyl chloride to afford 530 mg (56%) of the title compound of Step C, m.p. 129-130° C.
