Reaction Steps
Ethyl 5-(4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)-1,3,4-thiadiazole-2-carboxylate (Example 219; 0.530 g, 1.2 mmol) and lithium hydroxide (0.117 g, 4.9 mmol) were stirred in dioxane (5 ml) and water (0.5 ml) and heated to 50° C. for thirty minutes. The solution was acidified (pH 4) using 1 N HCl resulting in a precipitate. The solids were collected and purified using semi-preparative HPLC to give the title compound (0.025 g).
