Reaction Steps

A mixture of 1.0 g of 4-fluoro-1-nitro-2-(propan-2-yloxy)benzene, 634 mg of (R)-1,4-diazabicyclo[4,3,0]nonane and 1.04 g of potassium carbonate in 7 ml of DMSO is stirred at ambient temperature for 21 hours. The reaction medium is run into 15 ml of water and the mixture is then extracted three times with 30 ml of ethyl acetate. The organic phases are dried over magnesium sulfate, filtered and concentrated under vacuum, so as to obtain 1.44 g of (8aR)-2-[4-nitro-3-(propan-2-yloxy)phenyl]octahydropyrrolo[1,2-a]pyrazine in the form of an orangey-coloured oily residue.
