Yield:1421372-94-2 100%

Reaction Conditions:

with toluene-4-sulfonic acid in 1,4-dioxane at 105; for 2 h;

Steps:

2.1 (1) Preparation of Compound 11:

3-(2-Chloropyrimidin-4-yl)-1-methylindole 9 (5 g, 20.5 mmol) was placed in 1,4-dioxane, and compound 10 (3.8 g, 20.5 mmol) was added at room temperature, After p-toluenesulfonic acid monohydrate (4.7 g, 24.6 mmol) was added dropwise, the reaction was stirred at 105 °C for 2 hours. After the reaction is completed, the temperature is lowered to room temperature, and the solution is precipitated as a solid, which is suction filtered, and the cake is washed with ethyl acetate and dried. Dry to give a yellow solid 8.0 g, yield 100%.
