Methyl chloroformate → HCID 58852295, compound

Participants

Reaction Steps

To a solution of 2-{1-[1-(5-amino-indan-2-ylmethyl)-piperidin-4-yl]-5-methyl-1H-benzoimidazol-2-yl}-propan-2-ol (36 mg, 0.096 mmol), N,N-diisopropylethylamine (37 mg, 0.29 mmol) in THF (3 mL) was added methyl chloroformate (9 mg, 0.11 mmol). After stirring overnight, the reaction mixture was quenched with silica-supported diamine-3 (95 mg, Silicycle) to scavenge the excessive amount of methyl chloroformate. The mixture was filtered and concentrated in vacuo, and the residue was purified by flash chromatography eluent to afford (2-{4-[2-(1-hydroxy-1-methyl-ethyl)-5-methyl-benzoimidazol-1-yl]-piperidin-1-ylmethyl}-indan-5-yl)-carbamic acid methyl ester (20 mg, 59%) as white solid.
