Participants

Reaction Steps

3-[4-Carbamoyl-3-(phenylamino)-1H-pyrazol-1-yl]-3-(cyanomethyl)azetidinium trifluoroacetate (Intermediate #38-2) (25 mg, 0.060 mmol) was dissolved in MeCN (0.50 mL) and treated with DIPEA (0.020 mL, 0.12 mmol) and 1-fluoro-3-isocyanatobenzene (0.010 mL, 0.090 mmol). The reaction mixture was stirred at ambient temperature for 2 hours and then diluted with DMSO (1.0 mL) and purified directly 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 #38-1.
