Procedure

A mixture of methyl 3-iodo-α-methyl-D-phenylalaninate (0.73 g) in acetic acid (3 ml) and water (1 ml) was treated with sodium cyanate (0.4 g) and stirred for 2 days at 20° C. The solvents were removed under reduced pressure and the residue was diluted with EtOAc. The solution was washed with water, brine, dried (MgSO4) and evaporated to give the title compound (0.82 g) LCMS RT=2.74 min.
