Reaction Steps

A mixture of (R/S) tert-butyl methyl(2-(methyl((5-(4-nitrophenoxy)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-3-yl)methyl)amino)ethyl)carbamate (550 mg, 1.02 mmol, 1.00 equiv) and Raney/Ni (500 mg) in methanol (30 mL) was stirred under hydrogen at room temperature for 30 min. The catalyst was removed by filtration. The filtrate was concentrated under vacuum to give 400 mg (77%) of (R/S) tert-butyl 2-(((5-(4-aminophenoxy)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-3-yl)methyl)(methyl)amino)ethyl(methyl)carbamate as a colorless oil. 1H-NMR (300 MHz, CDCl3): δ 7.52-7.49 (m, 2H), 7.33-7.26 (m, 2H), 7.18-7.12 (m, 1H), 6.90-6.80 (m, 2H), 6.71-6.61 (m, 2H), 5.70-5.68 (m, 1H), 4.11-4.09 (m, 1H), 4.07-3.91 (m, 1H), 3.79-3.73 (m, 1H), 3.71-3.33 (m, 1H), 2.79 (s, 3H), 2.57-2.52 (m, 2H), 2.49-2.17 (m, 2H), 2.17-2.05 (m, 1H), 1.80-1.68 (m, 4H), 1.42 (s, 9H) ppm.
