Reaction Steps
5.0 G. of 2-(5H-dibenzo[a,d]cyclohepten-5-on-2-yl)propionic acid (preparation described infra) is suspended in 50 ml. of dioxane, added to excess ethereal diazomethane and stirred until dissolution is complete and evaporated to dryness. Purification as in part A on silica gel affords a nearly quantitative yield of 2-(5H-dibenzo[a,d]cyclohepten-5-on-2-yl)propionic acid methyl ester as in part A.
