Participants

Reaction Steps

Similarly 8 g (0.034 mole) of racemic 2-(4-morpholinylmethyl)-3,4-dihydro-2H-1,4-benzoxazine in about 130 ml. of 2N aqueous hydrochloric acid was treated with 1.3 g (0.019 mole) of sodium nitrite in about 100 ml of water at 0° C. to produce racemic 2-(4-morpholinylmethyl)-4-nitroso-3,4-dihydro-2H-1,4-benzoxazine, which was used as such in the next synthetic step without further purification or characterization.
