Exo-3-hydroxy-8-azabicyclo[3.2.1]octane hydrochloride

Conditions: temp:125.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-(n-propyl)amino-4-chloro-7-methyl-pyrrolo[2,3-d]pyrimidine (CXXIV) (1.0 g, 4.5 mmol) in n-butanol (10 mL) were added DIPEA (1.0 g, 7.8 mmol) and 8-aza-bicyclo[3.2.1]octan-3-ol hydrochloride (1.1 g, 6.7 mmol). The mixture was stirred at 125° C. for 16 h. After cooling to room temperature, water (20 mL) was added, and the mixture was extracted with EtOAc (3×50 mL). The combined organic layers were washed with water and then with a brine solution, and dried over anhydrous Na2SO4. The solvents were removed in vacuo and the resultant residue was purified by flash column chromatography (pet ether/EtOAc=6/1) to yield 8-(7-methyl-2-(propylamino)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-8-azabicyclo[3.2.1]octan-3-ol (CLIV) (800 mg, 57% yield) as a yellow solid. LCMS (ESI) m/z=316 (M+H)+. After cooling to room temperature the mixture was extracted with EtOAc (3×50 mL) The combined organic layers were washed with water with a brine solution, and dried over anhydrous Na2SO4 The solvents were removed in vacuo the resultant residue was purified by flash column chromatography (pet ether/EtOAc=6/1)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 8-Aza-bicyclo[3.2.1]octan-3-ol hydrochloride (5.1 g, 31.45 mmol)) and sodium carbonate (13.3 g, 125.8 mmol) are suspended in 150 ml of ethanol at room temperature. 2-Bromo-ethanol (4.4 ml, 62.9 mmol) is added dropwise within 20 minutes and the reaction mixture is refluxed for 15 hours. After cooling to room temperature the reaction mixture is evaporated under reduced pressure. The mixture is stirred with 200 ml of DCM and filtered. The clear filtrate is dried over anhydrous sodium sulfate, filtered, evaporated under reduced pressure and dried at high vacuum. the reaction mixture is refluxed for 15 hours is evaporated under reduced pressure filtered The clear filtrate is dried over anhydrous sodium sulfate filtered evaporated under reduced pressure dried at high vacuum
