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.
本发明提供了用于制备5-脂氧合酶激活蛋白(FLAP)抑制剂及其中间体的有用过程。具体来说,提供了用于制备3-[3-(叔丁基硫基)-1-[4-(6-乙氧基吡啶-3-基)苄基]-5-(5-甲基吡啶-2-基甲氧基)-1H-吲哚-2-基]-2,2-二甲基丙酸,无水Form C晶型的钠盐3-[3-(叔丁基硫基)-1-[4-(6-乙氧基吡啶-3-基)苄基]-5-(5-甲基吡啶-2-基甲氧基)-1H-吲哚-2-基]-2,2-二甲基丙酸酯,以及在该过程中有用的中间体。
