Reaction Steps

A suspension of 4-[2-(5-Chloro-2-fluoro-phenyl)-6,6-dimethyl-6,7-dihydro-5H-cyclopentapyrimidin-4-ylamino]-nicotinic acid (25 mg, 60.56 μmol) and Carbonyldiimidazole (20 mg, 121.11 μmol) in dry DMF (3 mL) was heated at 70° C. for 1 h then cooled to r.t. A stream of NH3 gas was passed through the solution for 30 min., giving clean conversion to the amide product. Evaporation of the solution, followed by HPLC purification gave, after lyophilization, the pure amide 62 as the TFA salt (20 mg).
