  Development of an Early Enabling Synthesis for PF-03052334-02: A Novel Hepatoselective HMG-CoA Reductase Inhibitor

  摘要：

  Early process development work toward a promising pyrazole-based HMG-CoA reductase inhibitor is described. PF-03052334-02 (1) was prepared in 14 synthetic steps with a 21% overall yield, highlighted by a modified three-step hydroxypyrazole formation in which the yield was improved from 37% to 73%, a Suzuki/ozonolysis pathway that streamlined the downstream chemistry, and a reversed Wittig olefination strategy that improved the key coupling step from 50% to 95% yield. Multiple process hazards and most chromatography steps were removed, and a highly effective active pharmaceutical ingredient (API) salt formation, purification, and isolation protocol was also developed.

  Novel compounds and pharmaceutical compositions useful as hypocholesterolemic and hypolipidemic agents are described. More specifically, potent inhibitors of the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (“HMG CoA reductase”) are described. Methods of using such compounds and compositions to treat subjects, including humans, suffering from hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, atherosclerosis, Alzheimer's Disease, benign prostatic hypertrophy (BPH), diabetes and osteoporosis are also described.
