Participants

Reaction Steps

A solution of 7.12 grams (0.0234 mol) of carbamate 3 in 50 ml of methanol and 35 ml of 6N hydrochloric acid is stirred at room temperature for 4 hours. The solution is neutralized, with cooling, by addition of 6N sodium hydroxide. The crystals formed are filtered off, washed with water and dried at 50° C. 4.55 g (yield 95%) of compound 4 are thus obtained in the form of a white powder.
