Related Products of 13745-17-0<\/a>, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 13745-17-0 as follows.<\/p>\n

General procedure: The fragment carboxylic acid (0.35 mmol) was dissolved in dimethylformamide (0.2 M, 1.75 mL), then 14 (42.6 mg, 0.35 mmol), HBTU (128 mg, 0.34 mmol), and HOBT (51.8 mg, 0.38 mmol) were added, followed by diisopropylethylamine (175 muL, 1.047 mmol). The reaction was stirred at 23 C for 16 h. TLC at 16 h showed conversion to product. The reaction was quenched with H2O (5 mL) and extracted with DCM (3 x 5 mL). The combined organic layers were washed with 1 M HCl (10 mL), saturated aqueous NaHCO3 (10 mL), and saturated aqueous NaCl (10 mL). The organic layer was dried over MgSO4, filtered, and evaporated. Purification with flash column chromatography with CH3OH\/CH2Cl2 ( CH3OH gradient 0 ? 5 %).<\/p>\n
