Procedure

Crude 2-(2-(2-(bis(tert-butoxycarbonyl)amino)pyrimidin-5-yl)-6-morpholino-9H-purin-9-yl)acetate (240 mg) was reacted with 3 eq of lithium hydroxide in 1:1 THF/water solution. After completion, the THF was concentrated in vacuo and the water solution was acidified to pH 2 using a concentrated HCl solution. The product precipitated as a fine white solid and was filtered to yield 2-(2-(2-(tert butoxycarbonylamino)pyrimidin-5-yl)-6-morpholino-9H-purin-9-yl)acetic acid (145 mg), of which 40 mg was subjected to General Procedure E and purified via reverse phase HPLC to give 19.5 mg 125 as a white solid. MS (Q1) 357.2 (M)+
