Abstract:
1. A process for producing a trifluoromethyl-substituted 2-alkoxyacetophenone derivative represented by the formula 9, comprising the steps of: (a) brominating a trifluoromethyl-substituted acetophenone, represented by the formula 1, by Br (b) reacting the brominated acetal with a metal alkoxide represented by the formula 7, thereby converting the brominated acetal into an ether represented by the formula 8; and (c) hydrolyzing the ether in the presence of an acid catalyst to remove an acetal group from the ether, thereby producing the 2-alkoxyacetophenone derivative, where m represents 1 or 2, where n represents an integer of from 2 to 4, where m and n are respectively defined as in the formulas 1 and 2, where R where m, n and R where m and R
