Participants

Reaction Conditions

Reaction Steps

841 mg (12.12 mmol) of hydroxylamine hydrochloride are suspended in 4 ml of DMF and cooled to 0° C. 303 mg (10.1 mmol) of 80% sodium hydride are added slowly. 500 mg (1.13 mmol) of (1RS,3aSR,4RS,6aSR)-4-(5-benzo[1,3]dioxol-5-ylmethyl-4-isopropyl-2,3,3-trimethyl-6-oxo-octahydro-pyrrolo-[3,4-c]pyrrol-1-yl)-benzonitrile are dissolved in DMF and added to the reaction mixture. The cooling is thereafter no longer applied. The mixture is stirred at room temperature for 5 days. Thereafter, it is filtered and the solvent is removed in a high vacuum. The mixture is purified by chromatography (RP18, gradient from water to methanol). (1RS,3aSR,4RS,6aSR)-4-(5-Benzo[1,3]dioxol-5-ylmethyl-4-isopropyl-2,3,3-trimethyl-6-oxo-octahydro-pyrrolo[3,4-c]pyrrol-1-yl)-N-hydroxy-benzimidamide is isolated in 66% yield. Colourless solid. ISP-MS: 479.4 ([M+H]+, 100).
