Chlorosuccinimide → 6-(((tert-butyl(dimethyl)silyl)oxy)methyl)-N-(5-chlorothiazol-2-yl)pyridin-2-amine

Participants

Reaction Steps

2 g of 6-(((tert-butyl(dimethyl)silyl)oxy)methyl)-N-thiazol-2-ylpyridin-2-amine obtained in Example 5-(2) was dissolved in 20 ml of 1,4-dioxane, and then 832 mg of N-chlorosuccinimide was added thereto at room temperature. The reaction mixture was heated under reflux for 2 hours, cooled to room temperature, diluted with ethyl acetate, and then washed with water and brine. The resulting organic layer was dried over anhydrous magnesium sulfate and filtered, and the filtrate was concentrated in vacuo to give the title compound.
