Hydrochloric Acid → HCID 24694245, compound

Participants

Reaction Steps

To the solution of the ester 14 (0.43 g, 2.0 mmol) in THF (18 mL) was added LiOH.H2O (0.17 g, 4 mmol) as a solution in 5 mL of H2O. The reaction mixture was stirred at room temperature and monitored by TLC. When no staring material was observed, the reaction mixture was acidified with 1N HCl, (˜4.5 mL) and concentrated under reduce pressure to remove the organic solvent. The mixture was diluted with 15 mL of H2O and extracted with EtOAc (2×120 mL). The organic layer was washed with brine, dried over Na2SO4, concentrated and dried under high vacuum over P2O5 to give 0.40 g (98% yield) of compound 15 which was used in subsequent reaction without further purification.
