Reaction Steps

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)+.
