5-AMINONAPHTHALENE-1-SUBSTITUTED (ALKOXY ETHYL) SULFANILAMIDES AND METHOD FOR PRODUCTION OF 5-AMINONAPHTHALENE-1-SUBSTITUTED (ALKOXY ETHYL) SULFONYL AMIDES Russian patent published in 1996 - IPC

Abstract RU 2053226 C1

FIELD: organic chemistry. SUBSTANCE: desired product is 5-NH2-naphthalene-SO2NHCH2CH2OR where R represents lower alkyl, lower alkyl oxyethylene. 5-substituted naphthalene sulfochloride is used as reagent 1, ethylene diamine being used as reagent 2. Reaction is carried out in the presence of triethylamine in the medium of lower alcohol. Thus obtained 5-substituted naphthalene-1-dimethyl sulfanilamide is treated by compound having formula R-OH where R is as it mentioned above. The process takes place at 60-110 C in the presence of BF3 acetate. EFFECT: improves quality of desired product, improves efficiency of method. 3 cl
