by filtration then we can obtain 94 g 2 3 bis 4 nitrophenoxy naphthalene 93 from which we can have it recrystallized by the glacial acetic acid to obtain 82 g yellow needlelike material having a melting point of 199 u00b0 200 u00b0 c in the 1000 ml flask there are added therein 61 g 2 3 bis 4 nitrophenoxy naphthalene 0 3 g pd c and 400 ml ethyl alcohol and gradually dropped therein 150 ml hydrazine at 80 u00b0 c to react for four hours thereafter if we filter the solution in the flask when hot we get 43 g 84 white slices of di ether amine having a melting point of 176 u00b0 177 u00b0 c using similar procedures we can get other kinds of his 4 aminophenoxy naphthalenes as follows 2 6 bis 4 aminophenoxy naphthalene having a yield of 72 85 and a melting point of 199 u00b0 200 u00b0 c 2 7 bis 4 aminophenoxy naphthalene having a yield of 75 85 and a melting point of 166 u00b0 167 u00b0 c 1 5 bis 4 aminophenoxy naphthalene having a yield of 72 82 and a melting point of 170 u00b0 171 u00b0 c 1 6 bis 4 aminophenoxy.
