6-(3-cyanopropyloxy)nicotinic acid (0.6 mmol) was coupled with 3-(3-pyridyl)-5-cyano-1-(4′-aminophenyl)-pyrazole (0.5 mmol) under standard EDC mediated conditions (Method A). Standard work-up gave the title compound (142 mg, 62%), m.p. 190-191° C. 1H NMR(CDCl3): δ 2.04-2.11 (m, 2H), 2.67-2.70 (7, J=7.1 Hz, 2H), 4.42-4.5 (t, J=6.2 Hz, 2H), 6.98-7.00 (d, J=8.7 Hz, 1H), 7.53-7.56 (m, 1H), 7.82-7.84 (d, J=8.9 Hz, 2H), 8.02-8.04 (d, J=8.9 Hz, 2H), 8.1 (s, 1H), 8.28-8.32 (m, 2H), 8.63-8.64 (m, 1H), 8.82-8.83 (m, 1H), 9.15-9.16 (m, 1H), 10.6 (s, 1H).
