Potassium Carbonate → HCID 86615225, compound

Participants

Reaction Steps

To a solution of mercapto-acetic acid methyl ester (1.0 g, 9.42 mmol) in dimethylformamide (10 mL) at room temperature was added potassium carbonate (1.69 g) followed by bromo-acetic acid tert-butyl ester (1.84 g, 9.42 mmol). The resulting suspension was stirred at ambient temperature overnight and then diluted with hexanes. The organic layer was washed with water three times and brine once, dried over sodium sulfate, filtered and concentrated to give a colorless oil, which was used directly in next step without purification. 1H NMR (CDCl3, 300 MHz) δ (ppm): 3.72 (s, 3H), 3.37 (s, 2H), 3.27 (s, 2H), 1.45 (s, 9H).
