Reaction Steps

A suspension of 2C (0.40 g, 1.87 mmol) in a mixed solvent of EtOH (2 mL) and conc. HCl (2 mL) was refluxed for 2 h. The resulting solution was allowed to cool to rt and concentrated under reduced pressure. The obtained solid was evaporated with toluene (2×) to yield compound 2D (0.25 g) as a solid.
