Procedure
1-(4-tert-Butylphenyl)-6-chloro-2-ethoxycarbonylmethyl-5-hydroxyindole-3-carboxylic acid ethyl ester (120 mg, 0.26 mmol, see step (b) above), 6-chloro-N,N-dimethylnicotinamide (72 mg, 0.39 mmol), K2CO3 (181 mg, 1.31 mmol) and DMF (3 mL) was heated at 115° C. for 96 h and filtered through Celite®. The solids were washed with EtOAc and the combined filtrates concentrated and purified by chromatography to give the sub-title compound. Yield 48 mg (78%).
