Procedure

To a solution of 6-(2-azidoethyl)-3-(2′,4′-difluorobiphenyl-3-yl)-6-phenyl-1,3-oxazinan-2-one (100 mg, 0.23 mmol) in 20:1 THF/H2O (3 mL) was added PPh3 (72 mg, 0.28 mmol). The reaction mixture was stirred at rt overnight. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel to afford 6-(2-aminoethyl)-3-(2′,4′-difluorobiphenyl-3-yl)-6-phenyl-1,3-oxazinan-2-one (30 mg, 31%). 1H NMR (400 MHz, CDCl3): δ=2.20-2.51 (m, 2H), 2.51-2.60 (m, 2H), 2.72 (m, 1H), 3.00 (m, 1H), 3.24 (m, 1H), 3.53 (m, 1H), 6.85-6.99 (m, 2H), 7.14 (m, 1H), 7.31-7.50 (m, 8H).
