Participants

Reaction Steps

tert-Butyl hexahydropyrrolo[3,4-c]pyrrole-2(1H)-carboxylate hydrochloride (10 g, 0.04 mol; see Preparation A above) and triethylamine (14 mL, 0.1 mol) were mixed in CHCl3 (100 mL). N-benzyloxy-carbonyloxy succinimide (11 g, 0.044 mol), dissolved in CHCl3 (100 mL), was added at 0–5° C. The mixture was allowed to slowly reach room temperature and was stirred at rt for 5 h. The reaction mixture was washed with water, dried (Na2SO4) and evaporated, giving the sub-title compound in quantitative yield.
