Reaction Steps

A 25 mL Schlenk flask was charged with (4-iodophenyl)(4-(tetrahydro-2H-pyran-2-yloxy)phenyl)methanone (408 mg, 1 mmol), Pd(PPh3)2Cl2 (18 mg, 0.025 mmol), CuI (10 mg, 0.05 mmol), Et3N (10 ml) and 1-(prop-2-ynyl)pyrrolidine (165 mg, 1.5 mmol). The flask was flushed with argon three times and the mixture was stirred at 90° C. for 3 h. The solvent was evaporated under vacuum and the residue was purified by columnchromatography to give the desired product (312 mg, 80% yield)
