1-Hydroxybenzotriazole hydrate (0.00158 mole) was added to a solution of compound 105 (0.00079 mole) in DCM (80 ml). Glycine methylester hydrochloride (0.00103 mole), N′-(ethylcarbonimidoyl)-N,N-dimethyl-1,3 propanediamine monohydrochloride (0.00103 mole) and 4-methylmorpholine (0.00103 mole) were added. THF (25 mm) was added. The reaction was stirred at room temperature for 3 days. The mixture was extracted with water. The organic phase was washed with saturated NaHCO3, 2N citric acid, saturated NaHCO3, dried over MgSO4, filtered, and concentrated, yielding 0.20 g of 1,1-dimethylethyl 2,3-dihydro-2-[4-[[(2-methoxy-2-oxoethyl)amino]carbonyl]-5-propyl-1H-imidazol-2-yl]-1H-indole-1-carboxylate (compound 109).
