A method of preparing a diphenyl ether compound of the formula (II) STR1 wherein X is F, Cl or Br; Z is hydrogen, halogen, NO2 of CN; and W is methyl, cyano, CH3 CO--, or a group --C--OR, wherein R is --OH; --OM wherein M is a cation; OR1 wherein R1 is an optionally substituted aliphatic radical; --NR2 R3 wherein R2 and R3 are each hydrogen or an optionally substituted aliphatic radical; or --NHSO2 R4 wherein R4 is alkyl of 1 to 6 carbon atoms, which comprises reacting a 3-X-substituted-4,5-difluorobenzotrifluoride with a salt of a 3,4-W,Z-substituted phenol. The invention further comprises novel 3-X-4,5-difluorobenzotrifluorides for use in the process.

Novel chemical compounds of the formula: SPC1 Wherein R is selected from the group consisting of hydrogen, alkyl from one to three carbon atoms, inclusive, phenyl, alkali metal, or an amine cation; X and Y can be the same or different and are selected from the group consisting of hydrogen, alkyl of from one to six carbon atoms, inclusive, cycloalkyl of 5 or 6 carbon atoms, inclusive, phenyl, hydroxyl, alkoxy having from one to three carbon atoms, inclusive, halogen, trifluoromethyl, cyano, carboxyamide and O C-OQ, EQU1 where Q is selected from the group consisting of hydrogen, alkyl from one to three carbon atoms, inclusive, alkali metal, and an amine cation, with the proviso that where R is hydrogen, alkali metal or an amine cation, then Q is the same as R, and where R is phenyl or alkyl from one to three carbon atoms, then Q is phenyl or alkyl from one to three carbon atoms; and Z is selected from the group consisting of hydrogen, alkyl from one to three carbon atoms, inclusive, and phenyl. The compounds are formulated with pharmaceutical carriers for oral or parenteral administration, with insufflation being the preferred method. The compositions are useful in the prophylactic treatment of sensitized humans and mammals for allergy and all anaphylactic reactions of a reagin or non-reagin mediated nature.
