Procedure

To a solution of N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-oxopropyl)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (27 mg, 46.0 mmol) in dichloroethane (4.76 mL) was added azetidin-3-ol hydrochloride (6.55 mg, 59.8 μmol.30). The mixture was stirred at 25° C. for 15 min, then sodium triacetoxyborohydride (14.6 mg, 69.0 μmol0) was added and stirring was continued for 18 h. The reaction mixture was diluted with saturated NaHCO3 solution and extracted with dichloromethane (5×20 mL). The organic layer was dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by chromatography (spherical silica 20-45 μm, 23 g, Versaflash Supelco) eluting with 0 to 5% over 20 min (MeOH containing 10% ammonium hydroxide)/dichloromethane to give traces of N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-(3-hydroxyazetidin-1-yl)propyl)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide and obtained mainly N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-hydroxypropyl)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (17 mg, 28.9 μmol, 62.7%) as an off-white solid. MS (M+H)+=589; 1H NMR (CDCl3) δ: 9.21 (s, 1H), 8.37 (s, 1H), 8.32 (d, J=2.3 Hz, 1H), 8.06 (s, 1H), 7.59 (d, J=9.1 Hz, 1H), 7.37 (dd, J=8.9, 2.1 Hz, 1H), 6.55 (t, J=74.4 Hz, 1H), 5.75 (s, 2H), 4.70 (t, J=6.6 Hz, 2H), 3.74 (t, J=5.7 Hz, 2H), 3.55-3.67 (m, 2H), 2.29 (quin, J=6.0 Hz, 2H), 1.64 (s, 9H), 0.91-1.05 (m, 2H), 0.00 (s, 9H).
