反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-(methylsulfonyl)phenol (100 mg, 0.58 mmol) and K2CO3 (276 mg, 2 mmol) in CH3CN (10 mL) was added ethyl 2-bromoacetate (115.2 mg, 0.69 mmol) at 25° C. The mixture was heated at 80° C. for 4 h, diluted with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated. The crude product was used in the next step without further purification. (140 mg, yield 94%). extracted with ethyl acetate The combined organic layers were washed with brine dried over sodium sulfate concentrated The crude product was used in the next step without further purification

実験手順: To a solution of 2-(methylsulfonyl)phenol (200 mg, 1.16 mmol) in CH3CN (10 mL) was added ethyl 2-bromo-2-methylpropanoate (232 mg, 1.39 mmol) and K2CO3 (690 mg, 5 mmol) at 25° C. The mixture was refluxed for 16 h and then quenched by addition of water (100 mL). The resulting mixture was extracted with ethyl acetate (2×50 mL). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give the title compound which was used in next step without further purification. The mixture was refluxed for 16 h quenched by addition of water (100 mL) The resulting mixture was extracted with ethyl acetate (2×50 mL) The combined organic layers were washed with brine (30 mL) dried over Na2SO4 concentrated

実験手順: To a solution of ethyl 2-(2-(methylsulfonyl)phenoxy)acetate (750 mg, 2.9 mmol) in EtOH (15 ml) was added 10% NaOH aqueous solution (15 mL) at 26° C. The mixture was stirred for 30 min and then concentrated and the residue diluted with water (20 mL) and washed with ethyl acetate (2×20 mL). The aqueous layer was then acidified with 2N HCL until pH 3 and then extracted with ethyl acetate (2×20 ml). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give the title compound which was used in next step without further purification. concentrated the residue diluted with water (20 mL) washed with ethyl acetate (2×20 mL) extracted with ethyl acetate (2×20 ml) The combined organic layers were washed with brine (30 mL) dried over Na2SO4 concentrated
