Procedure

4-[4-Carbamoyl-3-(phenylamino)-1H-pyrazol-1-yl]-4-(cyanomethyl)piperidinium trifluoroacetate (Intermediate #38-1) (20 mg, 0.05 mmol) was diluted with DMF (0.5 mL) and treated with cyclopropanecarboxylic acid (5 mg, 0.06 mmol), DIPEA (0.020 mL, 0.12 mmol) and 1,3,5,2,4,6-trioxatriphosphorinane-2,4,6-trioxide (0.040 mL, 0.060 mmol). The reaction mixture was heated to 40° C. and allowed to stir for 16 hours. The mixture was then cooled to ambient temperature, diluted with DMSO (1.0 mL), and purified by reverse-phase preparative HPLC (using a gradient elution of 5-95% MeCN/water, with 0.1% v/v NH4OH modifier). Desired fractions were identified, combined and concentrated in vacuo to afford the title compound, Example #34-1. 1H NMR (600 MHz, DMSO-d6): δ 9.09-9.00 (m, 1H), 8.50 (s, 1H), 7.55 (s, 1H), 7.48 (d, J=7.7 Hz, 2H), 7.26-7.17 (m, 2H), 7.15 (s, 1H), 6.80 (m, 1H), 4.09-3.90 (m, 2H), 3.18 (s, 2H), 2.47 (s, 2H), 2.35 (s, 2H), 2.07-1.97 (m, 2H), 1.95-1.87 (m, 1H), 0.74-0.62 (m, 4H).
