実験手順

To a solution of 2-(5-(3,8-diazabicyclo[3.2.1]octane-3-carbonyl)pyridin-2-ylamino)-7-cyclopentyl-N,N-dimethyl-7H-pyrrolo[2,3-d]pyrimidine-6-carboxamide (105 mg, 0.22 mmol) in dichloromethane (2 ml) 1-hydroxypropan-2-one (2 ml) was added and the resulting reaction mixture was stirred for 1H at room temperature. Sodium triacetoxyborohydride was added and the reaction mixture was stirred at room temperature overnight. When TLC/LCMS show completion the reaction mixture is diluted with dichloromethane, washed with sat NaHCO3 (2×) and brine. The combined aqueous layers back extracted with dichloromethane and the combined organic layers are dried over sodium sulfate, filtered, concentrated and purified by column chromatography (0-20% methanol/dichloromethane) which gave 7-cyclopentyl-2-(5-(8-(1-hydroxypropan-2-yl)-3,8-diazabicyclo[3.2.1]octane-3-carbonyl)pyridin-2-ylamino)-N,N-dimethyl-7H-pyrrolo[2,3-d]pyrimidine-6-carboxamide (39 mg, 33% yield). 1H NMR (400 MHz, CDCl3) δ ppm 9.07 (s, 1H) 8.85 (s, 1H) 8.57 (d, J=9.09 Hz, 1H) 8.45 (s, 1H) 7.78 (dd, J=8.59, 2.53 Hz, 1H) 6.48 (s, 1H) 4.81 (dq, J=9.09, 8.93 Hz, 1H) 4.48 (br. s., 1H) 3.75-3.30 (m, 6H) 3.23-3.00 (m, 7H) 2.69-2.50 (m, 3H) 2.16-1.97 (m, 5H) 1.97-1.66 (m, 6H) 1.10 (d, J=6.06 Hz, 3H); HR-MS (m/z MH+) 547.32 RT 2.54 min.
