Hydrochloric Acid → 10-Chloro-1-anthracenemethanol

Participants

Reaction Steps

A solution of ethyl 10-chloroanthracene-1-carboxylate (37B, 14.86 g, 0.052 mol) in THF (300 mL) was treated with LiBH4 (Alfa, 1.14 g, 0.052 mol) and refluxed for 16 h. The reaction mixture was poured into ice water and acidified with conc. HCl to pH=2. The solid was filtered, washed with H2O (500 mL), air dried and then chromatographed on a plug of SiO2 (500 g) using EtOAc as the eluting solvent. The solvent was removed by rotary evaporation to give a solid, which was crystallized from CCl4 to give 10.3 g (81%) of 10-chloro-1-anthracenemethanol mp 138°-140°, (C, H, Cl).
