Procedure
To a solution of 3-chloro-6-methanesulfonyl-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (131 mg, 0.5 mmol) in 1-methyl-2-pyrrolidinone (5 mL) was added ethanolamine (150 mg, 2.5 mmol, 5 eq) and the reaction mixture was heated to 50° C. After 1 hour, water (20 mL) was added, followed by ethyl acetate (20 mL). The layers were separated. The organic layer was washed with brine, dried over MgSO4, filtered and evaporated. The resulting yellow residue was purified by column chromatography (50% ethyl acetate-hexane) to give 2-(3-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-6-ylamino)-ethanol (100 mg, 87% yield); LC/MS (m/e)=228.2 (MH+), Rt=1.44 min.
