Procedure
A solution of 3-(1,2,3,4-tetrahydro-isoquinolin-7-yl)-3-(pyrid-4-yl)-propionic acid, enantiomer A {Reference Example 18(a)} in ethanol (50 mL) was treated with concentrated hydrochloric acid (two drops) and then heated at reflux temperature, under nitrogen, for 8 hours. The pH of the reaction mixture was adjusted to ˜5 by dropwise addition of sodium bicarbonate solution (5%) and this mixture was then evaporated to give the title compound which was used without further purification.
