Procedure
K2CO3 was added to a solution of 5-bromoindazole and in DMF. The mixture was heated to 105° C. After disappearance of 5-bromoindazole the reaction mixture was poured onto DCM/brine. The two layers were separated and the aqueous layer was extracted with DCM (2×) and checked by TLC. The combined organics were washed with H2O (2×) and brine and dried over Na2SO4. After filtration, the filtrate was concentrated and the resulting residue was purified by chromatography with 9.5:0.5 hexane/EtOAc to provide desired product (14p).
