Hydrochloric Acid → HCID 19080433, compound

Participants

Reaction Steps

To a solution of 1.518 g (3.66 mmol) of the product of Step A dissolved in 8.0 mL of methanol was added 1.0 mL of a 5.0M solution of aqueous sodium hydroxide. The reaction was stirred at room temperature and monitored by TLC (80:15:1 CHCl3 --MeOH--NH4OH). After 1.5 hours the reaction was judged to be complete and the reaction mixture was adjusted to pH=5 with 1.0N HCl. The reaction mixture was then partitioned between EtOAc and water, separated, dried (MgSO4), filtered, and evaporated. The residue was purified on a silica gel flash chromatography column eluted with CHCl3 --MeOH--NH4OH (80:15:1); evaporation of the purified fractions and drying in vacuo afforded the title compound as an amorphous foam.
