Hydrochloric Acid → HCID 67170201, compound

Participants

Reaction Steps

The compound of step 1 (20 g, 89.2 mmol) was dissolved in DMF (100 ml) and cooled in an ice bath. Potassium carbonate (18.4 g, 134 mmol) and, immediately thereafter, benzyl bromide (15.2 g, 89.2 mmol) were added. This mixture was stirred for 30 min at room temperature, poured on a mixture of 2 N hydrochloric acid and diethyl ether, filtered and washed repeatedly with diethyl ether. The combined ethereal phases were washed with water, dried over sodium chloride, decanted and evaporated to dryness. The residue was purified by silica gel chromatography (HEP/EA gradient) to yield the title compound (21 g).
