Chlorosuccinimide → HCID 178501059, compound

Participants

Reaction Steps

A solution of trans-4-(4-methyl-oxazol-2-yl)-cyclohexanecarboxylic acid methyl ester (277 mg, 1.24 mmol) and N-chlorosuccinimide (182 mg, 1.36 mmol) in N,N-dimethylformamide (2.5 ml) was stirred for 6 h at room temperature. The reaction mixture was partitioned between tert-butyl methyl ether (25 ml) and 0.1 M aqueous sodium hydroxide solution (25 ml). The layers were separated. The aqueous layer was extracted with one 25-ml portion of tert-butyl methyl ether. The combined organic layers were washed with three 25-ml portions of water, dried over anhydrous sodium sulfate and concentrated in vacuo to give the crude title compound (285 mg, 89%) as light yellow solid, which was used in the next step without further purification. MS m/e: 258 ([M+H]+)
