Reaction Steps

To a solution of 7-methylspiro[2H-benzofuran-3,1′-cyclopropane]-4-ol (Intermediate 13, 176 mg, 1 mmol) in dry Acetonitrile (4 ml) potassium carbonate (207 mg, 1.5 mmol) and then 2-chloro-5-nitropyrimidine (159 mg, 1 mmol) were added and the reaction mixture was stirred for 24 hours at 80° C. After cooling the reaction mixture was quenched with water (2 ml), diluted with brine (10 ml) and extracted with ethyl acetate (2×20 ml). The organic layer was dried over sodium sulfate, filtered and evaporated affording the title compound (258 mg) as an orange solid that was used in the next step as crude material without further purification.
