Procedure

A solution of 0.15 g (0.24 mmols) of 8 and 25 mg of Pd—C catalyst in 20 mL of anhydrous ethanol was subjected to hydrogenation conditions at 1 atm pressure for 2 h. The catalyst was filtered off and the crude product was reslurried in 98:2 mixture of diethylether:ethanol to afford 90 mg of the phosphate 9 as off white solid.
