On October 22, 2009, Hahn, Michael G.; Becker, Eva-Maria; Knorr, Andreas; Schneider, Dirk; Stasch, Johannes-Peter; Schlemmer, Karl-Heinz; Wunder, Frank; Stoll, Frederike; Heitmeier, Stefan; Muenter, Klaus; Griebenow, Nils; Lampe, Thomas; El Sheikh, Sherif; Li, Volkhart Min-Jian published a patent.HPLC of Formula: 64987-16-2 The title of the patent was Preparation of phthalazinones as soluble guanylate cyclase inhibitors. And the patent contained the following:
Title compounds I [X = L1-M-L2CO2H; L1 = bond, methylene, etc.; M = phenylene, 5 or 6-membered heteroaryl with provisos; L2 = bond, methylene with provisos; A = 5-7 membered heterocycle ring with provisos; R1 = H, alkyl, cycloalkyl; R2 = H, halo, CN, etc.; R3 = alkyl, alkenyl, etc.] and their pharmaceutically acceptable salts and formulations were prepared For example, NaOH/dioxane/H2O mediated saponification of ester II [Y = Me] afforded acid II [Y = H]. In soluble guanylate cyclase inhibition assays, 48-examples of compounds I exhibited MEC values ranging from 0.1-300 nM. The experimental process involved the reaction of Methyl 2-(2-aminothiazol-4-yl)acetate(cas: 64987-16-2).HPLC of Formula: 64987-16-2
