Procedure

To a solution of 2-(2-aminopyrimid-5-yl)-4-(1,1-dimethylethyl)-5-oxo-morpholine (2.0 g) in 100 ml of dry tetrahydrofuran, 10 ml of a 2.0M solution of BH3.Me2S in tetrahydrofuran is added dropwise under nitrogen. The reaction mixture is then heated at reflux for 5 hours followed by treatment with methanol (25 ml) at reflux for 3 hours. The solution is concentrated and the residue chromatographed on silica gel to give the titled compound.
