Reaction Conditions:
with potassium carbonate in N,N-dimethyl-formamide at 60; for 18 h;
Steps:
13.1 Step 1: Synthesis of 4- (2,4-dichlorophenoxy) benzaldehyde
P-fluorobenzaldehyde (2.48g, 20.00mmol), 2,4-dichlorophenol (3.32g, 20.00mmol), potassium carbonate (11.00g, 80.00mmol), and N, N-dimethylformamide (30mL) Add it to a 250 mL single-necked flask, and react for 18 h in an oil bath at 60 ° C. Add ice water (200 mL) to the reaction solution, stir for 10 min to precipitate a solid, filter, and wash the cake with water (50 mL x 3)The title compound was obtained (yellow solid, 4.1 g, yield: 77%).
