Reaction Steps

3-[4-Amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentyl (2S)-2-[(tert-butoxycarbonyl)amino]-3-methylbutanoate (35 mg, 0.060 mmol) was dissolved in ethyl acetate (2.5 ml). Hydrogen chloride gas was passed through for 5 minutes. The flask was capped and the solution stirred for additional 30 minutes. Diethyl ether was added and precipitate formed. The solid was collected by filtration to give 3-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentyl (2S)-2-amino-3-methylbutanoate hydrochloride. The structure was confirmed by 1H NMR and LC/MS (MH+=486).
