PROCESSES FOR THE PREPARATION OF 5-LIPOOXYGENASE ACTIVATING PROTEIN INHIBITORS AND THEIR INTERMEDIATES

摘要

The present invention provides processes useful for preparing 5-lipoxygenase activating protein (FLAP) inhibitors and their intermediates. In particular, processes for preparing 3-[3-(tert-butylsulfanyl)-1-[4-(6-ethoxy-pyridin-3-yl)benzyl]-5-(5-methyl-pyridin-2-yl-methoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic acid, the anhydrous Form C polymorph of sodium 3-[3-(tert-butylsulfanyl)-1-[4-(6-ethoxy-pyridin-3-yl)benzyl]-5-(5-methyl-pyridin-2-yl-methoxy)-1H-indol-2-yl]-2,2-dimethyl-propionate, and intermediates useful in said processes are provided.
