Procedure

To a solution of 2-(tetrazolo[1,5-a]pyrid-6-yl)-4-(1,1-dimethylethyl)-5-oxo-morpholine (2.09 g) in 100 ml of dry tetrahydrofuran (THF), a 2.0M solution of BH3.Me2S in tetrahydrofuran (10 ml) was added dropwise under nitrogen. The reaction mixture was then heated at reflux for 5 hours. The mixture was cooled and treated with 25 ml of methanol. The mixture was then heated at reflux for 3 hours. The solution was concentrated under reduced pressure and the residue (2.45 g) purified by column chromatography (95:5 methylene chloride:ethanol) on silica gel to give 1.99 g of product. Mass spectrum (FAB) 262 (M+1).
