(2,2,2-三氟-1-苯乙基)三氟甲磺酸盐

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a stirred solution of 2(R)-amino-3-cyclopropylmethylsulfanylpropan-1-ol (80.5 mg, 0.5 mmol) in anhydrous THF (3 mL) were added activated 4 Å molecular sieves (250 mg) and N-methylmorpholine (51 mg, 0.5 mmol). After stirring for 10 min, trifluoromethanesulfonic acid 2,2,2-trifluoro-1-phenylethyl ester (190.5 mg, 0.5 mmol) was added and the reaction was stirred at room temperature for 2 days. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by flash column chromatography to afford the desired mixture of diastereomers of 2(R)-3-cyclopropylmethyl-sulfanyl-2-(2,2,2-trifluoro-1(RS)-phenylethylamino)propan-1-ol. LC-MS: 318.3(M-1), 320.8(M+1). the reaction was stirred at room temperature for 2 days The reaction mixture was filtered the filtrate was concentrated The residue was purified by flash column chromatography to afford the desired
