Procedure

5-(Ethylamino)-4-methyl-4′-(morpholinomethyl)[1,1′-biphenyl]-3-carboxylic acid (300 mg, 0.84 mmol) was dissolved in DMSO (2 mL) and 3-(amino methyl)-4,6-dimethylpyridin-2(1H)-one (257 mg, 1.69 mmol) was added to it. After 15 minutes stirring at room temperature PyBOP (660 mg, 1.26 mmol) was added to the reaction mixture and stirring was continued for overnight. After completion, the reaction mass was poured into ice, extracted with 10% MeOH/DCM (5 times). Combined organic layer was washed with water and dried over sodium sulphate. Removal of the solvent under reduced pressure followed by solvent washings afforded the title compound (100 mg, 24%).
