PROCEDURE

实验过程

To 2-(5-amino-3-tert-butyl-pyrazol-1-yl)-ethanol (3.42 g, 0.019 mol), add TBDMSCl (3.38 g, 1.2 equiv.) and imidazole (3.18 g, 2.5 equiv.) in DMF (7 mL) and stir overnight at room temperature under N2. Dilute the reaction with ethyl acetate and water. Wash the organic layer with water then saturated aqueous saturated sodium chloride and then dry over magnesium sulfate, filter, and concentrate in vacuo to give a solid (5.5 g, 99%) which is used without further purification. MS (ES), m/z 298 (M+1).
