N-(4-(Dimethylphosphoryl)phenyl)-9-vinyl-9H-purin-6-amine (Example 3, 1 mmol), 2-chloro-3-iodo-4-methylpyridine compound (1.3 mmol), diisopropylethyl amine (3 mmol), palladium acetate (0.05 mmol), tri-o-tolylphosphine (0.1 mmol) in DMF (5 mL) was thoroughly purged with argon for 10-15 min. and sealed and heated for 120° C. for 18 h. until the starting materials disappeared. The reaction mix. was passed through celite, and washed with dichloromethane containing 30% methanol. The filtrate was concentrated in vacuo. The residue was purified by Biotage-S column chromatography using 1/1 hexane ethyl acetate, ethyl acetate and 1-10% methanol containing ethyl acetate: MS [M+H]+ 439.
