Sodium Hydroxide → HCID 178432838, compound

Participants

Reaction Steps

A mixture of trans-4-(5-chloro-4-methyl-oxazol-2-yl)-cyclohexanecarboxylic acid methyl ester (285 mg, 1.11 mmol) in 1,4-dioxane (5.5 ml) and 2 M aqueous sodium hydroxide solution (5.5 ml, 11 mmol) was stirred for 4 h at room temperature. The reaction mixture was partitioned between ethyl acetate (25 ml) and water (25 ml). The aqueous layer was acidified to pH 2. The layers were separated. The aqueous layer was extracted with two 25-ml portions of ethyl acetate. The combined organic layers were washed with one 10-ml portion of brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give the title compound (245 mg, 91%) as white solid. MS m/e: 242 ([M−H]−)
