(verify) synthesis synthesis: potassium amide was made from the reaction of potassium metal with liquid ammonia. the coupling between the carbanion created from diphenylmethane (1) and ethyl 2-furoate (2) gives 2-furyl benzhydryl ketone, cid:63950182 (3). the was reacted with concentrated liquid ammonia in methanol solvent in an autoclave. the product of this step was 2-benzhydrylpyridin-3-ol, cid:125491889 (4). reduction of the pyridine gave 2-(diphenylmethyl)piperidin-3-ol, cid:209477 (5).
