実験手順
As shown in FIG. 9B (Scheme 4), the synthesis of 1-(3-aminopropyl)-3-benzylimidazolidin-2-one (35) will be performed by treating the starting material N1-benzylethane-1,2-diamine with diethoxymethoxyethane to form 1-benzyl-4,5-dihydro-1H-imidazole. The imidazole intermediate will be treated with BuLi (forming a lithiate) followed by quenching with water to form the final intermediate 1-benzylimidazolidin-2-one. Treating the imidazolidinone with NaH followed by Br—(CH2)3—N(SiMe3)2 under reducing conditions will afford the intermediate 35.
