The synthetic route is as follows.

To a solution of ethyl2-chloronicotinate (2 g, 10.78 mmol) and 3-phenyl-1H-pyrazo1e (2.33 g, 16.16 mmol) in DMF (30 mL) was added K2C03 (4.47 g, 32.33 mmol)and Kl (1.79 g, 10.78 mmol). The mixture was stirred at 130 oc for 16h. The reaction wasfiltered, the filtrate was added I-hO (100 mL), extracted with EA (30 mL x2), the organicphase was washed with brine ( l 00 mL ), filtered, and concentrated. The residue was purifiedby flash silica gel chromatography (ISCO; 40 g SepaFlash Silica Flash Column, Eluent of15(% Ethyl acetate/Petroleum ethergradient 40 mUmin). Compound 113A (1 g, yield:28.5%) was obtained as a white solid. 1H NMR (400MHz, CDCh) 8 8.49 (dd, J = 1.7, 4.6Hz, lH), 8.42 (d, J”‘ 2.4 Hz, 1H), 7.94 (dd, J ‘” 1.7, 7.6 Hz, lH), 7.89- 7.78 (m, 2H), 7.40 (t,J “‘ 7.3 Hz, 2H), 7.33 (br d, J ‘” 7.3 Hz, H-I), 7.29 – 7.23 (m, HI), 6.79 (d, J “‘ 2.7 Hz, HI),4.45- 4.25 (m, 2H), 1.14 (t, J = 7.2 Hz, 3H).
