Reaction Steps
According to example 54, 0.73 g of 2-cyclohexyl-L-phenylalanine.HCl was treated with 25 mL of isobutylene in 25 mL of 1,4-dioxane in the presence of 0.4 mL of conc. H2SO4. Work-up followed by acidification of the free amine with ethereal HCl afforded 0.70 g (80%) of tert-butyl 2-cyclohexyl-L-phenylalaninate.HCl as a yellow foam.
