Participants

Reaction Steps

A mixture of 6-hydroxy-1-indanone (250 g, 1687 mmol) (634549, commercially available from Sigma-Aldrich, St. Louis, Mo., USA), t-butyldiphenylchlorosilane (487 g, 1772 mmol) and imidazole (138 g, 2025 mmol) in degassed DMF (900 mL) was heated at 60° C. for 16 hours. The mixture was then concentrated to remove most of DMF, diluted with ether (3000 mL), filtered, and concentrated to give the initial product H1.1 (674 g, 100% yield) which was used in the next step reaction without further purification. MS ESI (pos.) M/E: 409 (M+Na).
