实验过程

1-[3-(Benzyloxy)propyl]-3,5-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (Compound 43C, 560 mg, 1.5 mmol) was hydrogenated using the procedure from Compound 38A to afford 421 mg of the desired title compound (99%). 1H NMR (400 MHz, CD3OD) δ 4.08 (t, J=7.1 Hz, 2H), 3.50 (t, J=6.1 Hz, 2H), 2.40 (s, 3H), 2.27 (s, 3H), 1.95 (t, J=6.7 Hz, 2H), 1.30 (s, 12H). MS (ESI): m/z=280.37 [M+H]+. UPLC: tR=1.29 min (UPLC-TOF: polar—2 min).
