The invention provides a process for preparing compounds, as a single enantiomer or mixture of enantiomers, represented by the formula: ##STR1## in which: X and Y are independently hydrogen, hydroxy, lower alkyl, lower alkoxy or halo, or X and Y taken together is methylenedioxy or ethylene-1,2-dioxy, and Z is --SO.sub.2 R or --C(O)NR.sup.3 R.sup.4, in which; R is lower alkyl, optionally substituted phenyl, --(CH.sub.2).sub.m OR.sup.1 or --NR.sup.1 R.sup.2 wherein m is an integer of 1 to 6 and R.sup.1 and R.sup.2 are independently hydrogen or lower alkyl; and R.sup.3 and R.sup.4 are independently hydrogen, alkyl, optionally substituted phenyl or phenyl lower alkyl; or R.sup.1 and R.sup.2 taken together with the nitrogen to which they are attached or R.sup.3 and R.sup.4 taken together with the nitrogen to which they are attached represent a heterocycle of the formula: ##STR2## wherein A is --CH.sub.2 --, --NR.sup.1 -- or oxygen; and novel intermediates.
