Participants

Reaction Steps

1-Hydroxybenzotriazole hydrate (0.00036 mole), glycine methylester, hydrochloride (0.00047 mole), 4-methylmorpholine (0.00055 mole), and N′-(ethylcarbonimidoyl)-N,N-dimethyl-1,3-propanediamine monohydrochloride (0.00047 mole) were added to compound 117 (0.00036 mole) dissolved in DCM (30 ml) at 0° C. The mixture was allowed to warm to room temperature under nitrogen, and stirred overnight. The mixture was extracted with water, saturated NaHCO3, 2N citric acid, then saturated NaHCO3, dried, filtered, and concentrated, yielding 0.100 g (69%) of 1,1-dimethylethyl 2,3-dihydro-2-[4-[[(2-methoxy-2-oxoethyl)amino]carbonyl]-1H-imidazol-2-yl]-1H-indole-1-carboxylate (compound 118).
