The present invention relates to processes for preparing (3-oxo-2,3-dihydro-1H-isoindol-1-yl)acetylguanidine derivatives of the formula I via 3-hydroxy-2,3-dihydro-1H-isoindol-1-one derivatives or 3-(2-carbamoylphenyl)-acrylic ester derivatives as intermediates, to a process for optical resolution, and to intermediates of the process according to the invention.

Process for preparing (3-oxo-2,3-dihydro-1H-isoindol-1-yl) acetylguanidine derivatives

A method and apparatus for preventing board warpage during the application and curing or drying of liquid epoxies, or the like, on printed circuit boards using a clamping fixture assembly, which includes at least one clamping fixture support and at least one clamping fixture overlay. If desired, a plurality of printed circuit boards may be processed using an appropriate clamping fixture assembly. Furthermore, the clamping fixture may be constructed so a slight bow or curvature thereof can counter either a convex or concave bow or curvature of the printed circuit board. In the method, at least one printed circuit board is mounted to a clamping fixture support whereby a clamping fixture overlay is placed on top of the first printed circuit board.
