47% [Referential Example 119]; 1-Benzylhexahydro-1H-1,4-diazepin-5-one ; [] Concentrated sulfuric acid (25 mL) was added to 1-benzyl-4-piperidone (10.14 g) in acetic acid (50 mL) at room temperature, and sodium azide (3.880 g) was added thereto at 0C over a period of 2 hours, followed by stirring at 5C for 25 hours. The reaction mixture was alkalinized through addition of aqueous sodium hydroxide, followed by partitioning by use of chloroform. The aqueous layer was extracted with chloroform. The organic layers were combined, and washed with saturated brine, and then dried over sodium sulfate anhydrate, followed by filtration. The solvent was evaporated under reduced pressure, and then the residue was purified through silica gel column chromatography (chloroform - methanol), to thereby give the title compound as a solid (5.081 g, 47%).1H-NMR(400MHz,CDCl3)delta: 2.50-2.70(6H,m), 3.20-3.35(2H,m), 3.60(2H,s), 6.07(1H,br), 7.20-7.40(5H,m).

To this mixture was then added 200 mL of dioxane and the resulting solution was again evacuated and flushed 3* times with nitrogen gas. The mixture was allowed to stir at 75 C. overnight during which time the mixture turned from brown to bright yellow suspension. The mixture was cooled and diluted with dichloromethane and then was filtered through a pad of celite. The filtrate was removed under reduced pressure and the residue was purified by flash column chromatography eluding with 50% EtOAc/Hex to give compound 1 as an off-white solid (63%).
