39093-93-1, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 39093-93-1
Into a 250-mL round-bottom flask, was placed a solution of (2S)-4-[(tert-butyldiphenylsilyl)oxy]-2-[[4-(4-fluorophenyl)phenyl]formamido]butanoic acid (2 g, 3.60 mmol, 1.00 equiv) in tetrahydrofuran (50 mL), DEPBT (1.62 g, 5.41 mmol, 1.50 equiv). This was followed by the addition of imidazole (370 mg, 5.44 mmol, 1.50 equiv). stirred for 40 min at 0¡ã C. To this was added a solution of thiomorpholine-1,1-dioxide (890 mg, 6.58 mmol, 1.50 equiv) in tetrahydrofuran (20 mL) dropwise with stirring at 0¡ã C. in 30 min. The resulting solution was stirred for 16 h at 25¡ã C. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 50 mL of H2O. The resulting solution was extracted with 3¡Á50 mL of ethyl acetate and the organic layers combined. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:1). This resulted in 2 g (82percent) of (1) as a off-white solid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 39093-93-1, we look forward to future research findings about .
