In the formulas, R1=H or C1-3 alkoxy; R2=C1-4 alkyl  or  C1-3 alkoxy (if R1 is C1-3 alkoxy, R2 is not  C1-4  alkyl).  Pref.  the using amount of the alkalimetal hydroxide  is  1-5  equivalence(s) relative to 1 equiv. of the cpd. (II). The cpd. (I) is  useful  as an intermediate in the manufacture of medicines or cosmetics.
