Procedure

4-(2-(2-(1H-tetrazol-5-yl)ethyl)-5-(4-methoxyphenyl)-1H-pyrrol-1-yl)-3-methylbenzoic acid (130 mg, 0.332 mmol) was dissolved in anhydrous THF (3 mL). CDI (68 mg, 0.419 mmol) was added in three portions at room temperature and stirred at this temperature for 1 h. The resultant yellow solution was added dropwise to 25% ammonium hydrate (3 mL) at 0° C. After the addition was complete, the mixture was allowed to warm to room temperature and stirred for 2 h. The mixture was evaporated in vacuo and the residue was purified by prep-HPLC to afford 2H, R2=4-methoxyphenyl as a yellow solid (7 mg, 5.4%).
