YieldReaction ConditionsOperation in experiment
80% With toluene-4-sulfonic acid In toluene at 130℃; for 4h; Dean-Stark; Inert atmosphere; 3 (Example 3)Synthesis of 3-methoxy-1-butyl-3-butenoate Vinylacetic acid synthesized in Example 1 (formula (1-0), 7.75 g, 90 mmol), 3-methoxy in a 100 mL two-necked flask equipped with a Dimroth reflux condenser, a Dean-Stark trap, and a nitrogen introduction tube -1-Butanol (9.37 g, 90 mmol), p-toluenesulfonic acid monohydrate (0.86 g, 4.5 mmol) and toluene (35 mL) were added. The two-necked flask was immersed in an oil bath, and the temperature of the oil bath was raised to 130 ° C. While maintaining the same temperature, the mixture was stirred for 4 hours under a nitrogen stream to distill off the by-produced water. The two-necked flask was cooled to room temperature (25 ° C.), washed three times with saturated aqueous sodium hydrogen carbonate (10 mL), further washed twice with distilled water (10 mL), and then dried over magnesium sulfate. After removing the magnesium sulfate, the solution was concentrated under reduced pressure. The resulting concentrated residue was distilled under reduced pressure in the same manner as in Example 2 to isolate compound (1-2a) (3-methoxy-1-butyl-3-butenoate) (12.33 g, yield 80%). The physical properties of the obtained compound (1-2a) are shown below.
