methyl 2-(2,2,2-trifluoroethoxy)acetate

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of methyl 2-(2,2,2-trifluoroethoxy)acetate (8.26 g, 47.98 mmol) and methanol (16 mL) was added sodium hydroxide (1.92 g, 47.98 mmol) in methanol (16 mL). After stirring for 18 hours, the reaction was concentrated and ether (170 mL) was added. The mixture was cooled to 0° C. and concentrated sulfuric acid (2.15 g, 43.9 mmol) in ether (7.5 mL) was slowly added. The resulting mixture was stirred for 18 hours, filtered and concentrated to give the title compound as a colorless oil (7.15 g, 94%), MS(CI): 159(M+H); H-NMR (300 MHz, DMSO-d6): 4.14(q, J=9.3 Hz, 2H), 4.21(s, 2H), 12.92(s, 1H). the reaction was concentrated ether (170 mL) was added The resulting mixture was stirred for 18 hours filtered concentrated

実験手順: To a mixture of sodium hydride (1.648 g, 68.66 mmol) in tetrahydrofuran (220 mL) at 0° C. was added 2,2,2-trifluoroethanol (5.0 mL, 68.66 mmol). After 5 minutes, the reaction was allowed to warm to room temperature and methyl 2-bromoacetate (6.2 mL, 65.39 mmol) was added. After stirring for 72 hours, the mixture was filtered through diatomaceous earth with ether washes. The filtrate was concentrated and distilled to afford the title compound as a colorless oil (8.26 g, 73%), bp 155°-60° C., MS(CI): 173(M+H); H-NMR (300 MHz, DMSO-d6): 3.68(s, 3H), 4.16(q, J=9.2 Hz, 2H), 4.33(s, 2H). the mixture was filtered through diatomaceous earth with ether washes The filtrate was concentrated distilled
