Reaction Conditions

Reaction Steps

A solution of (4-{[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-ylcarbamoyl]-methyl}-phenyl)-carbamic acid tert-butyl ester (2.20 g, 4.10 mmol) in a solution of a 4.0N aqueous hydrochloric acid solution in dioxane (37.0 mL) was stirred at 25° C. for 1 h. A suspension formed during this time. The reaction mixture was cooled to 0° C. The resulting solid was collected by filtration, washed with dioxane and cold diethyl ether, and dried in vacuo to afford N-[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-yl]-2-(4-amino-phenyl)-acetamide, hydrochloride salt (1.73 g, 89%); LRMS for C23H23FN5O3 (M+H)+ at m/z=438.
