Abstract
There is disclosed a compound represented by formula (I): ##STR1## wherein R.sup.1 represents a tert-butyl group, a phenyl group having an alkoxy group with 1 to 18 carbon atoms in the paraposition, or an indoline-1-yl group; R.sup.2 represents a group substitutable on the benzene ring; and n is an integer of 0 to 4, provided that when R.sup.1 represents a tert-butyl group, n is not 0. The compound may be used as a synthesis intermediate from which a yellow coupler can be synthesized in a simple manner. Using the compound, a yellow coupler can be readily produced on an industrial scale with the short process.
