Procedure
The title compound was prepared in the same manner described 5-(4-Amino-3-fluorophenoxy)nicotinic acid methyl ester, substituting 4-amino-2-fluorophenol for 4-amino-3-fluorophenol. 1H NMR (DMSO-d6) δ 7.96 (d, J=1.5 hz, 1H), 7.64 (d, J=3.0 Hz, 1H), 6.88 to 6.87 (m, 1H), 6.16 (t, J=8.7 Hz, 1H), 5.79 to 5.69 (m, 2H), 4.07 (s, 2H), 3.09 (s, 3H); TLC (50% EtOAc/Hex), Rf=0.31.
