Procedure

A solution of 2-(3-(2′,4′-difluorobiphenyl-3-yl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)acetic acid (30 mg, 0.072 mmol), HOBt (18 mg, 0.144 mmol), EDCl (30 mg, 0.144 mmol) and DIEA (0.2 ML) in anhydrous CH2Cl2 (3 mL) was stirred at 0° C. under NH3. Then the solution was stirred at rt overnight. Solvent was removed in vacuo, the residue was purified by HPLC to get 2-(3-(2′,4′-difluorobiphenyl-3-yl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)acetamide (1.68 mg, 6%). 1H-NMR (400 MHz, CDCl3): δ=2.58 (m, 2H), 2.80-3.00 (m, 2H), 3.27 (m, 1H), 3.50 (m, 1H), 6.00 (s, 1H), 6.36 (s, 1H), 6.78-6.90 (m, 2H), 7.05 (m, 1H), 7.23-7.55 (m, 9H).
