The solid N-[(1,1-dimethylethoxy)carbonyl]-4-(1,3,6-trimethyl-2,4-dioxo-5-pyrimidinyl)-L-phenylalanine 1-(acetoxy)ethyl ester (1.4 mmol, 0.705 g) was treated with 4N hydrochloric acid in dioxane (20 mmol, 5 mL) at room temperature and the solution was stirred for 2 h as a white precipitate was formed. The mixture was diluted with diethyl ether and dichloromethane and the solids were collected by filtration washing with diethyl ether. After air drying, 0.63 g (99% yield) of 4-(1,3,6-trimethyl-2,4-dioxo-5-pyrimidinyl)-L-phenylalanine 1-(acetoxy)ethyl ester hydrochloride was obtained as an amorphous gray solid. ES-HRMS m/e calcd for C20H26N3O6 (M+H) 404.1816, found 404.1818.
