Procedure

A suspension of EXAMPLE 198B (500 mg), morpholine (80 mg), palladium (II) acetate (22 mg), biphenyl-2-yldi-tert-butylphosphine (50 mg) and cesium carbonate (427 mg) in anhydrous tetrahydrofuran (6 mL) was heated at 50° C. overnight. The reaction mixture was cooled to room temperature and diluted with ethyl acetate. The organic phase was washed with water, brine, dried over anhydrous sodium sulfate, filtered and concentrated. The crude material was purified by flash column purification with 30-50% ethyl acetate/hexane to afford the title compound.
