Reaction Steps

A 5.2-g portion of the p-ethoxycarbonylphenyl 5-nitro-1,2,3,4-tetrahydro-1-naphthoate obtained above was catalytically reduced with 5% palladium-carbon in ethyl acetate. After removal of the catalyst by filtration, the ethyl acetate was removed by distillation to obtain p-ethoxycarbonylphenyl 5-amino-1,2,3,4-tetrahydro-1-naphthoate which was dissolved in diethyl ether and dry gaseous hydrogen chloride was introduced thereinto to obtain 4.5 g of p-ethoxycarbonylphenyl 5-amino-1,2,3,4-tetrahydro-1-naphthoate hydrochloride, m.p. 218°-219° C.
