Reaction Conditions

Temperature100 °C

Reaction Steps

A mixture of 2-(1-benzothien-2-yl)-4-chloropyrido[2,3-d]pyrimidine (18.2 mg, 0.06 mmol), 5-aminoindazole (40 mg, 0.3 mmol) and potassium carbonate (83 mg, 0.6 mmol) in dioxane (20 mL) was heated to 100° C. and continued for 24 h. After removal of the solvent, the crude product was purified by silica gel column chromatography (gradient from 20% to 80% EtOAc/hexane) to give the product (1.0 mg, 4.0%); HPLC/MS: (M+H)+ 395.2 m/z; Retention time (LC-MS)=2.75 min.
