Procedure

A mixture of methyl N-(aminocarbonyl)-3-iodo-α-methyl-D-phenylalaninate (0.82 g) and potassium carbonate (624 mg) in dimethyl sulfoxide (5 ml) was heated to 110° C. for 3 h and then allowed to cool to 20° C. overnight. The mixture was diluted with EtOAc and washed with 2M HCl, brine, dried (MgSO4) and evaporated to dryness to give the title compound (521 mg) LCMS RT=2.61 min
