Reaction Conditions:

with caesium carbonate;copper(II) oxide in 1-methyl-pyrrolidin-2-one at 195; for 0.833333 h;Inert atmosphere;

Steps:

107.1 Step 1: Synthesis of compound 1-bromo-3-phenoxybenzene
Dissolve m-dibromobenzene (3.9g, 17mmol) and phenol (1.3g, 14mmol) in N-methylpyrrolidone (45mL),Then copper oxide (0.11g, 1.4mmol) and cesium carbonate (5g, 15mmol) were added, protected by nitrogen, and heated to 195 ° C for 50min.Stop heating, cool to room temperature, filter through diatomaceous earth, and dilute with water (100 mL).Extract with ethyl acetate (80 mL × 3), collect the organic phase, dry over anhydrous sodium sulfate, filter, and concentrate.Silica gel column chromatography (PE) was separated and purified to obtain 3.4 g of light yellow liquid. Yield: 96%.
