A process for making ##STR4## in an overall reaction which comprises contacting ##STR5## in a reaction zone at a temperature between 20.degree. and 250.degree. C. to obtain a reaction mixture and contacting said reaction mixture with an inorganic base at a temperature between 20.degree. C. and 250.degree. C. in a second part of the overall reaction to thereby obtain the compound of formula I, wherein
- R.sup.1 is lower alkyl or hydrogen;
- R.sup.2 is lower alkyl or hydrogen;
- R.sup.3 is lower alkyl, hydrogen, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 halo alkyl, trifluoromethyl, nitro, or halo;
- R.sup.4 is lower alkyl, hydrogen, or C.sub.1 -C.sub.4 alkoxy;
- R.sup.5 is lower alkyl or hydrogen;
- and
- X and Y are halo.
