Reaction Steps

A solution of methyl 2-[2-[(benzyloxy)carbonyl]amino-3-(1-trityl-1H-5-imidazolyl)propanoyl][(E)-2-butenyl]aminoacetate (2.23 g, 3.4 mmol) in MeOH (20 mL )/dioxane (15 mL) was treated with 2 N NaOH (7.0 mL, 14.0 mmol) and stirred at room temperature for 0.5 hour. After adding 2 N HCl (7.0 mL, 14.0 mmol), the mixture was stripped to a solid. This was mixed with EtOAc/THF and filtered to remove NaCl. Removal of the solvent under reduced pressured left 2.06 g (94.5% yield) of the product as a white solid foam. MS, rn/z 643 (M+H+).
