1-Bromo-2-butanone → 4-Ethyl-2-(4-methyl-2-nitro-phenyl)-thiazole

Participants

Reaction Steps

The procedure described in Example 15-1, was followed but 4-methyl-2-nitro-thiobenzamide (56) was used instead of 4-trifluoromethyl-2-nitro-thiobenzamide, and 1-bromo-2-butanone was used instead of 1-bromo-3-methyl-butan-2-one, which gave the title compound (90 mg, 91%). LC/MS: (Method I): tR=1.55 min, >90%, m/z (ESI+)=249 (MH+).
