Participants

Reaction Steps

10.5 g. of the above 1-(2-amino-3-nitrophenoxy)-2,3-epoxy-propane were stirred for 30 hours at ambient temperature with 35 g. tert.-butylamine and 100 ml. ethanol. Subsequently, the reaction mixture was evaporated to dryness, the residue was dissolved in 200 ml. 2N hydrochloric acid, a small amount of undissolved material was filtered off with suction and the hydrochloric acid solution was shaken out several times with chlorofrom. 100 ml. 10N aqueous sodium hydroxide solution were then added to the aqueous acidic solution and the mixture extracted several times with ether. The ethereal extracts were dried over anhydrous sodium sulfate and then evaporated to about 100 ml., the base thereby separating out as a fine crystalline slurry by the use of ice cooling. There were obtained 10.5 g. 1-tert.-butylamino-2-hydroxy-3-(2-amino-3-nitrophenoxy)-propane; m.p. 75° - 77°C.
