Sodium hydride → ethyl 2-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]propionate

Participants

Reaction Steps

Sodium hydride (120 mg, of a 60% dispersion in mineral oil) was added to a mixture of 4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine (906 mg) in dry dimethyformamide (30 ml) and the mixture was stirred under nitrogen for 30 minutes at ambient temperature. A solution of ethyl 2-bromopropionate (543 mg) in dry DMF (10 ml) was added dropwise via a syringe over 10 minutes. The mixture was stirred at ambient temperature for 2 hours and then left for 18 hours. The mixture was evaporated under vacuum and the residue was washed with water to give a solid which was triturated with ether and filtered to give ethyl 2-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]propionate, m.p. 139-140° C.
