                                    Heavy metal assisted halogen displacement on 2-halobenzoylpyrroles (2 and 3) leads to a simple synthesis of FPL 64176 (1) and a variety of analogues (4-10). The difluoro derivative (4), EC50 1nM, and the amino linked analogue (7), EC50 2.7nM, are presently the most potent calcium channel activators known.
