Sodium Bicarbonate → HCID 57474997, compound

Participants

Reaction Steps

A solution of methyl-4-(1,4-dioxa-8-azaspiro[4.5]dec-8-yl)-benzoate (4.87 g, 17.56 mmol) in 10% aqueous sulfuric acid (50 mL) and THF (50 mL) was stirred at ambient temperature for 72 hours. The reaction mixture was neutralized by cautious addition of NaHCO3 and simultaneously diluting with water. The aqueous mixture was extracted with EtOAc (2×75 mL) and the combined organic extracts were dried (MgSO4), filtered, and concentrated to give the title compound as an off-white, amorphous solid (4.06 g, 99%) which was used without further purification.
