Iodoacetamide → 2-((2-Methylbenzoyl)imino)-5-nitro-3(2H)-thiazoleacetamide

Participants

Reaction Steps

Sodium hydride in mineral oil (2.1 g, 60% w/w) was added in portions to a stirred suspension of 2-methyl-N-(5-nitro-2-thiazolyl)benzamide (10.5 g) in N,N-dimethylformamide (100 ml). When the evolution of hydrogen ceased, 2-iodoacetamide (11.1 g) was added in portions. The mixture was stirred at room temperature for ca 1 hr., then poured into ice-water. Recrystallization of the separated solid from acetic acid afforded 2-[(2-methylbenzoyl)imino]-5-nitro-4-thiazoline-3-acetamide, m.pt 248°-250°.
