[0036]
[0037] Synthesis of Step 1 Intermediate 3
[0038]Benzomorpholine (1.00 g, 7.40 mmol) and methyl 4-bromomethylbenzoate (1.69 g, 7.40 mmol) were dissolved in 30 mL of DMF, then anhydrous potassium carbonate (2.04 g, 14.8 mmol) was added, The temperature was raised to 80°C for reaction. After 6 hours of reaction, TLC detected that the reaction was complete. The reaction solution was cooled to room temperature, and the reaction solution was poured into 150 mL of water. A large amount of solid was precipitated, and 1.88 g of an off-white solid was obtained by filtration, with a yield of 89.7%.
[0039] Synthesis of Step 2 Intermediate 4
[0040] Dissolve intermediate 4 (1.88g, 6.64mmol) in 20mL of ethanol, add 10mL of 2N sodium hydroxide solution, stir at room temperature for 2h, TLC detects that the reaction is complete, distill off ethanol under reduced pressure, add water and adjust with 3N hydrochloric acid When the pH reached 4-5, a large amount of solids were pr...
