Procedure

To a suspension of compound 17a (100 mg) and K2CO3 (69 mg) in MeCN was added compound 18a (0.0353 mL) and the mixture was stirred at room temperature for 30 min. The reaction was concentrated and the residue was diluted with EtOAc and water. The organics were concentrated and purified by flash column chromatography (silica gel, 8% MeOH/EtOAc) to afford compound 355 (85 mg). MS m/z (M+H+) 495.6.
