Participants

Reaction Steps

Add potassium carbonate (40 mg, 0.29 mmol) and bromoethanol (0.018 mL, 0.26 mmol) to a solution of (S)-9-[(3,5-Bis-trifluoromethyl-benzyl)-(2H-tetrazol-5-yl)-amino]-2,3,6,7,8,9-hexahydro-1H-5-aza-cyclohepta[f]indene-5-carboxylic acid isopropyl ester (50 mg, 0.086 mmol) in dimethylformamide (0.3 mL). Stir at room temperature for 18 hrs in a sealed tube. Then add bromoethanol (0.018 mL, 0.26 mmol) and stir for 2 hrs. Add a 1N solution of hydrochloric acid and extract with dichloromethane. Dry the organic phase over anhydrous sodium sulfate, filter and concentrate in vacuo. Purify the residue using silica gel cartridge, eluting with ethyl acetate/hexanes to afford the title compound (26 mg, 49%). MS (ES+): 627 (M+H).
