Reaction Steps

Ethyl iodide (51 μL, 0.63 mmol, 8.0 eq) is added at room temperature to a stirred solution of 6-methoxy-quinoline-3-carboxylic acid trans-4-[(2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-amino]-cyclohexylmethyl ester (37 mg, 0.08 mmol, 1.0 eq) in N,N-dimethylformamide (0.5 mL), followed by silver oxide (73 mg, 0.31 mmol, 4.0 eq). After 4 hours stirring at room temperature, the reaction mixture is filtered through decalite and the mother liquid is concentrated to give a residue that is purified by preparative HPLC to afford 6-methoxy-quinoline-3-carboxylic acid trans-4-[(2,3-dihydro-benzo[1,4]dioxin-6-ylmethyl)-ethyl-amino]-cyclohexylmethyl ester as an off-white lyophilizated solid (9 mg, 14% yield)
