标题:Chemical Development Of Zd9331: Synthesis Of A Bromomethylquinazolinone Avoiding A Nonselective Radical Bromination
摘要:An Efficient Regiospecific Synthesis Of Zd9331 Pivaloyloxymethyl (Pom) Bromide (4) Has Been Accomplished Via Zd9331 Quinacetate Hcl (15) Avoiding A Nonselective Bromination. The Original Route Used A Radical Bromination On A Substrate With Three Methyl Groups,Which Generated A Range Of Bromomethyl Derived Compounds That Carried Through To The Final Active Pharmaceutical Ingredient (Api). A Strategy,Based On The Zinin Reaction,Was Developed To Synthesize The Required Bromomethyl Compound In A Regioselective Manner. This Approach Was Successfully Scaled To Manufacture A Tonne Of Material.
