Reaction Steps

A solution of 5-methyl-3-phenylpyrrolidin-3-ol (9 mg, 0.05 mmol) and triethylamine (28 μL, 0.2 mmol, 4 equ.) in DMF (0.2 mL) was added to a solution of 5-(4-methoxyphenyl)-1H-pyrazole-4-carboxylic acid (11 mg, 0.05 mmol, 1.2 equ.) and 1-propanephosphonic acid cyclic anhydride (70 μL, 0.115 mmol, 2.3 equ., 50% solution in ethyl acetate) in DMF (0.1 mL) at rt. The reaction mixture was stirred at 60° C. overnight. The crude product was purified by RP-HPLC. After evaporation of the solvents the product was dried in vacuum to yield the title compound (3 mg). MS (ESI, pos. ion) m/z: calcd for C22H23N3O3: 377.1739, found 377.1739.
