The title compound was synthesized as described for Intermediate example I-81 in 67% yield starting from ethyl 6-chloronicotinate and 2-methoxyethanol. The reduction was performed using 3 equiv of lithium hydroxide while heating to 40° C. over weekend. The final aqueous solution was extracted with ethyl acetate in order to collect the product; 1H NMR (400 MHz, DMSO-d6) δ ppm 8.70 (d, 1 H), 8.13 (dd, 1 H), 6.91 (d, 1 H), 4.42-4.47 (m, 2 H), 3.62-3.68 (m, 2 H), 3.29 (s, 3 H); MS (ESI) m/z 198[M+H+].
