Reaction Conditions:

with tetrakis(triphenylphosphine) palladium⁽⁰⁾;potassium carbonate in 1,4-dioxane;water at 84 - 88; for 9 h;Inert atmosphere;

Steps:

1.1 Step 1. Preparation of 2-(4-bromophenyl)naphthalene

Under the protection of argon, to a 300mL three-necked flask connected with a mechanical stirrer, condenser, and thermometer, add 2-naphthaleneboronic acid (30.0g),P-bromoiodobenzene (49.35g), Pd(PPh3)4 (4.60g), potassium carbonate (24.11g), dioxane (150ml), water (60ml),After refluxing the reaction at 84-88°C for 9h, the temperature was lowered to room temperature, filtered, and the filter cake was washed with water until neutral (pH=7),After adding 250 ml of toluene to the filter cake under reflux and water separation, it passes through a holding column, the column liquid is recrystallized, and dried to obtain 45.0 g of light yellow solid 2-(4-bromophenyl)naphthalene (ie, intermediate 1), yield 91.11%.
