A solution of Example 132 (40 mg, 0.01 mmol) and 3-methylaniline (0.012 mL, 0.01 mmol) in DMF (1 mL) was heated in a Smith synthesizer microwave to 180° C. for 22 minutes and partitioned between water and ethyl acetate. The aqueous phase was extracted three times with ethyl acetate and the combined extracts were washed with water and brine, dried (Na2SO4), filtered and concentrated. The concentrate was purified by flash column chromatography on silica gel with 8% methanol/dichloromethane to provide the desired product (15 mg).
