Diisopropylethylamine → Methyl 3-{2-[2-(2-{2-[2-(2-{[2-(2,6-bis(hydroxymethyl)pyridin-4-yloxy)ethyl](methyl)amino}-1,1-dimethylethylsulphanyl)acetylamino]ethoxy}ethoxy)ethoxy]ethoxy}propanoate

Participants

Reaction Steps

73.7 mg of methyl 3-[2-(2-{2-[2-(2-iodoacetylamino)ethoxy]ethoxy}ethoxy)ethoxy]propanoate in solution in 1 ml of DMF and 39 μl of DIPEA are added to 45 mg of 4-{2-[(2-mercapto-2-methylpropyl)(methyl)amino]ethoxy}-2,6-bis(hydroxymethyl)pyridine in solution in 1 ml of DMF. After 24 h at AT, the mixture is concentrated under RP and purified by flash chromatography on silica (Analogix Super Flash SiO2 SF25-8 g), using a gradient from 0 to 10% of methanol in DCM. 53 mg of methyl 3-{2-[2-(2-{2-[2-(2-{[2-(2,6-bis(hydroxymethyl)pyridin-4-yloxy)ethyl](methyl)amino}-1,1-dimethylethylsulphanyl)acetylamino]ethoxy}ethoxy)ethoxy]ethoxy}propanoate are thus obtained.
