실험 절차
A mixture of Example 65 (2 g, 3.58 mmol), 5-trimethylstannyl-pyrimidine (1.3 g, 5.35 mmol, prepared according to patent WO 95/06636) and tetrakis(triphenylphosphine)palladium(0) (620 mg, 0.54 mmol) in toluene (50 ml) was refluxed for 10 h under a nitrogen atmosphere. After cooling to room temperature, the insoluble material was filtered off and washed twice with toluene. The toluene layers were concentrated in vacuo. The resulting orange oil (3.1 g) was chromatographed over silica gel (eluent: EtOAc) to yield the above-titled compound as a white solid after crystallization from MeOH (430 mg), mp=228° C.
