[0418] Preparation 76: 5-Chloro-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid (1-(S)-(4-fluorobenzyl)-2-{4-[methyl(2-nitrate phenylsulfonyl)amino]piperidin-1-yl}-2-oxoethyl)amide

[0419]

Embodiment 231

[0420] From 2-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propanoic acid (Example 231) Example 230) and N-methyl-2-nitro-N-piperidin-4-ylbenzenesulfonamide hydrochloride (Preparation 75). m / z(ES + )=643.36[M+H] + .

[0421] Preparation 77: Thiomorpholine 1,1-dioxide

[0422]

[0423] To a solution of thiomorpholine (1.0 g, 9.69 mmol) in acetic acid (11.5 mL) cooled to 0 °C (ice bath) was added aqueous hydrogen peroxide (30% w / v, 4 mL) and the reaction was heated to 100 ℃ 16h. The mixture was cooled and the solvent was removed in vacuo, then the residue was triturated with methanol to give a white precipitate. The solid was filtered and washed with methanol to afford the title compound as an off-white powder. m / z(ES + )=136.06[M+H] + .

Abstract

Compounds represented by Formula (I): or pharmaceutically acceptable salts thereof, are inhibitors of glycogen phosphorylase and are useful in the prophylactic or therapeutic treatment of diabetes, hyperglycemia, hypercholesterolemia, hyperinsulinemia, hyperlipidemia, hypertension, atherosclerosis or tissue ischemia e.g. myocardial ischemia, and as cardioprotectants.

Description

technical field [0001] The present invention relates to pyrrolopyridine-2-carboxamides. In particular, the present invention relates to pyrrolopyridine-2-carboxamides as inhibitors of glycogen phosphorylase. Background technique [0002] Insulin-dependent type 1 diabetes and non-insulin-dependent type 2 diabetes are difficult to treat despite clinically acceptable treatment options including diet, exercise, hypoglycemic drugs, and the availability of insulin. Treatment is patient-dependent, so there is still a need for new hypoglycemic agents, especially those that are better tolerated and have fewer side effects. [0003] The liver and certain other organs produce glucose by breaking down glycogen or by synthesizing glucose from small molecule precursors—thus raising blood sugar levels. The breakdown of glycogen is catalyzed by glycogen phosphorylase. Thus, inhibition of glycogen phosphorylase ("GP") can reduce elevated blood glucose levels in diabetic patients. [0004...
