Versuchsvorschrift

To a solution of 1-[2-(3-amino-phenyl)-5-tert-butyl-2H-pyrazol-3-yl]-3-[4-(pyridin-4-yloxy)-phenyl]-urea (100 mg, 0.23 mmol), 3-[(tert-butyldimethylsilyl)oxy]-1-propanal (47 mg, 0.25 mmol, 1.1 eq), and sodium triacetoxyborohydride (67 mg, 0.32 mmol, 1.4 eq) in anhydrous THF (2 mL) was added acetic acid (16 mg, 0.27 mmol, 1.2 eq). The reaction mixture was stirred under N2 at room temperature for 2 h. The reaction mixture was quenched with saturated NaHCO3 and extracted with EtOAc. The combined organic phases were washed with brine, dried over Na2SO4 and concentrated at reduced pressure. The crude residue was purified by MPLC (eluting with 40:60 to 60:40 EtOAc/hexanes) to give 117 mg (84%) of 1-(5-tert-butyl-2-{3-[3-(tert-butyl-dimethyl-silanyloxy)-propylamino]-phenyl}-2H-pyrazol-3-yl)-3-[4-(pyridin-4-yloxy)-phenyl]-urea. 1H-NMR (DMSO-d6) δ 9.17 (s, 1H), 8.40 (dd, J=1.5 & 4.6 Hz, 2H), 8.31 (s, 1H), 7.48 (d, J=8.8 Hz, 2H), 7.17 (t, J=8.1 Hz, 1H), 7.07 (d, J=8.8 Hz, 2H), 6.85 (dd, J=1.6 & 4.9 Hz, 2H), 6.61-6.56 (m, 3H), 6.32 (s, 1H), 5.92 (t, J=5.6 Hz, 1H), 3.66 (t, J=6.1 Hz, 2H), 3.07 (q, J=7.5 Hz, 2H), 1.72 (quintet, J=6.8 Hz, 2H), 1.26 (s, 9H), 0.84 (s, 9H), 0.02 (s, 6H); MS LC-MS [M+H]+=615.4, RT=3.28 min.
