A solution of (4-(4-amino-3-fluorophenoxy)pyridin-2-yl)methanol (750 mg, 3.2 mmol) and Et3N (821 mg, 8 mmol) in DMF (10 ml) at 0° C. was treated with tert-butyldimethylsilyl chloride (624 mg, 4.16 mmol). The resulting solution was stirred at RT for 4 hours. The solvent was removed in vacuo and the residue was purified by silica gel column chromatography to provide 4-(2-((tert-butyldimethylsilyloxy)methyl)pyridin-4-yloxy)-2-fluorobenzenamine (370 mg, 33% yield). 1H NMR (400 MHz, DMSO-d6) δ 8.32 (d, J=5.6 Hz, 1H), 7.02 (s, 1H), 6.67-6.82 (m, 4H), 4.76 (s, 2H), 3.71 (s, 2H), 0.89 (s, 9H), 0.07 (s, 6H); MS (ESI) m/z: 349.2 (M+H+).
