Diazomethane → HCID 53703941, compound

Participants

Reaction Steps

A solution of 320 mgm (7.6 millimols) of diazomethane (prepared from 2.14 gm of p-toluenesulfonyl-methylnitrosoamide in 30 ml of ether and 0.4 gm of potassium hydroxide in 10 ml of 96% ethanol and subsequent distillation) was added, while stirring, to a suspension of 2.3 gm (7.5 millimols) of [1-(2'-fluoro-4-biphenylyl)-ethylsulfinyl]-acetic acid (m.p.: 164°-165° C.) in 20 ml of ether. The acid dissolved, accompanied by nitrogen evolution. After the reaction was finished, the mixture was evaporated, and the residue was recrystallized from benzene cyclohexane (1/5). Yield: 2.0 gm (83.5% of theory); m.p.: 75°-77° C.
