実験手順

To 5-iodo-7-triisopropylsilanyl-7H-pyrrolo[2,3-d]pyrimidine (38, 0.37 g, 0.92 mmol) in a round bottom flask, 1.1 mL of tetrahydrofuran was added and the mixture cooled to −25° C. Isopropylmagnesium chloride (0.49 mL, 2.0 M in tetrahydrofuran, 0.97 mmol) was added and the reaction stirred, coming to 0° C. The reaction was cooled to −25° C. and (5-formyl-6-methyl-pyridin-2-yl)-(6-methoxy-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (74, 0.300 g, 0.839 mmol) in 2.5 mL of tetrahydrofuran was added. The reaction was stirred, coming to 0° C., then poured into aqueous saturated sodium bicarbonate and ethyl acetate. The organic layer was washed with brine, then dried over sodium sulfate, filtered and the filtrate adsorbed onto silica. This was purified by silica gel column chromatography eluting with 10-80% ethyl acetate in hexanes. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (75, 317 mg). MS (ESI) [M+H+]+=634.09.
