Yield:2447-54-3 88.8%
Reaction Conditions:
with boron trifluoride diethyl ether complex in 1,4-dioxane at 0 - 20;Solvent;Reagent/catalyst;
Steps:
1.4; 2.4; 3.4 (4) Preparation of sanguinarine:
Add sanguinarine (0.2g, 0.57mmol), dioxane (2mL) to the reactor, and dropwise add at 0°C boron trifluoride diethyl etherate (0.1618g, 1.14mmol), naturally warmed to room temperature for reaction, followed by TLC until no raw material remained. Destroyed with dilute hydrochloric acid, adjusted to alkali, extracted with dichloromethane, dried over anhydrous Na 2 SO 4 , and subjected to silica gel column chromatography to obtain 0.17 g of pale yellow solid sanguinarine with a yield of 88.8% and HPLC purity of 99.3%.
