Steps:

1; 1a; 1b Example 1a: Synthesis of Compound 5

In a 1000ml autoclave, put 100g of high-purity cardanol (97%purity) and 200mL of ethanol, and add a ruthenium carbon catalyst with a 10% ruthenium content of 5% of the raw material to ensure the airtightness of the device; first replace the kettle with nitrogen The inner gas is 3 times, and then replaced with hydrogen 3 times; start the stirrer and heat up, when the temperature rises to 100-110 ° C, after it is stabilized, pass hydrogen to 9.0-10.0 MPa, react for 1 hour, cool down and discharge; reduce The ethanol was recovered by pressure concentration to obtain 97.2 g of a white solid with a yield of 94.0% and a purity of 98%.
