실험 절차

To a solution of 5-Iodo-7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidine (38, 4.00 g, 9.97 mmol) in 5.00 mL of tetrahydrofuran at −20° C. under nitrogen, isopropylmagnesium chloride (5.80 mL, 2.0 M in tetrahydrofuran, 11.6 mmol) was added slowly. The reaction was allowed to warm to 0° C. over 70 minutes, then cooled to −20° C., followed by addition of 2-methylsulfanyl-pyrimidine-5-carbaldehyde (54, 1.12 g, 7.26 mmol) in 15.0 mL of tetrahydrofuran. The reaction was allowed to warm to room temperature over 1 hour, then poured into aqueous ammonium chloride and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered and the filtrate was concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with 20-100% ethyl acetate in hexane. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (55, 2.75 g).
