ABSTRACT:
An 1-amido-3-(2-hydroxyphenoxy)-2-propanol derivative represented by the following formula (1),wherein cycle A may have further 1 to 4 substituents, and said substituent means a substituent selected from the group consisting of saturated or unsaturated C1-4 alkyl group, aralkyl group in which alkyl moiety has 1 to 4 carbon atoms, aryl group, halogen atom, halogenated C1-4 alkyl group, C2-5 alkanoyl group, mono or dialkylcarbamoyl group in which alkyl moiety has 1 to 4 carbon atoms, cyano group and nitro group, and the substituents at positions 3 and 6, or at positions 4 and 5 on the cycle A are different each other. Other ring may be fused at positions 3 and 4, or at positions 5 and 6 on the cycle A to form a condensed polycyclic hydrocarbon with the cycle A. R1is alkanoyl group or aroyl group, and R2is hydrogen atom, alkanoyl group or aroyl group, or R1and R2may be combined together with the N atom to form a cyclic imido group, which is useful as an intermediate of medicines, etc.
