Procedure

44 g (about 0.18 mol) of crude or pure 6-benzyl-5,7-dioxo-octahydropyrrolo[3,4-b ]pyridine are reduced with 15.2 g (0.40 mol ) of lithium aluminum hydride in 390 ml of absolute tetrahydrofuran in the course of 10 hours in accordance with the working instructions of Example Ic. 4.4 g of a colorless oil having a boiling point of 93°-95° C./0.06 mbar are obtained on distillation.
