Reaction Steps

6.6 g (0.035 mol) of 1,1,3,3-tetramethyl-1,3-dihydroisoindole N-oxide are hydrogenated to saturation in 66 ml of ethanol over 0.12 g of PtO2 at atmospheric pressure. The catalyst is filtered off and the solvent is evaporated on a rotary evaporator, after which the crystalline residue is recrystallized from a little dichloromethane. This gives 5.2 g (78%) of N-hydroxy-1,1,3,3-tetramethyl-1,3-dihydroisoindole which is obtained in the form of colourless crystals; melting point: 128–130° C.
