Reaction Steps

To a solution of 4-(4-oxo-3,4-dihydro-quinazolin-2-ylmethyl)-cyclohexanecarboxylic acid (275 mg, 1.05 mmol), EDC (200 mg, 1.05 mmol) and HOAt (142 mg, 1.05 mmol) in anhydrous DMF (4 mL) was added 2-fluorobenzylamine (131 mg, 1.05 mmol), and the resulting reaction mixture was stirred for 1 h. The reaction mixture was partitioned between saturated aqueous NaHCO3 and EtOAc, and the organic layer washed 2× with water. The EtOAc was dried with MgSO4 and concentrated to give a yellow solid. Preparative chromatography eluting with chloroform:methanol gave the cis 4-(4-oxo-3,4-dihydro-quinazolin-2-ylmethyl)-cyclohexanecarboxylic acid 2-fluoro-benzylamide as a white solid: mass spectrum m/z 394 [(M+H)+; calcd for C23H24FN3O2: 393].
