- Suggest reagents to make the drug phenaglycodol by the route below.Indicate the order of basicity of: aniline, 2-propylamine and 1-(2-aminophenyl)ethanone. Explain.Compound A has the molecular formula C14H25Br and was obtained by thereaction of sodium acetylide with 1,12-dibromododecane. On treatment ofcompound A with sodium amide, compound B (C14H24) was obtained. Ozonolysisof compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation ofcompound B over Lindlar palladium gave compound C (C14H26), andhydrogenation over platinum gave compound D (C14H28). Further, C yieldedO=CH(CH2)12CH=O on ozonolysis. Assign structures to compounds A through Dso as to be consistent with the observed transformations.
