| Synthesis | Example 3: Synthesis of compounds shown in chemical formula 11
According to reaction scheme 3, the steps for the synthesis of the compound shown in chemical formula 11 are as follows:
Step 1: Synthesis of intermediate G
105.0 g (628.4 mmol) of ethyl bromoacetate and 994.67 g (12.6 mol) of pyridine were suspended in an appropriate amount of solvent. The suspension was stirred and reacted at room temperature for 2 hours. Upon completion of the reaction, 1,000 mL of diethyl ether was added to the reaction mixture to induce precipitation of the product. The precipitated pale yellow solid was separated by filtration and washed with diethyl ether. After drying, 152.3 g of Intermediate G was obtained in 98% yield. | | References | [1] Patent: US2012/313091, 2012, A1. Location in patent: Page/Page column 69-70
