What is tert-Butyl (S)-(5-benzyl-5-azaspiro[2.4]heptan-7-yl)carbamate?
Synthesis
3.75 g of 5-benzyl-5-azaspiro[2.4]heptan-7-amine was added to the reaction flask, followed by 35 mL of ethanol, 3.75 g of triethylamine and 6.5 g of Boc2O.Stir the reaction at room temperature for 12-14 hours, concentrate, add ethyl acetate, and then use aqueous lemon solution, sodium bicarbonate solution, and saturatedWashed with brine, dried, concentrated and dried to give tert-Butyl (S)-(5-benzyl-5-azaspiro[2.4]heptan-7-yl)carbamate.The yield was 98.2%.![Carbamic acid, [(7S)-5-(phenylmethyl)-5-azaspiro[2.4]hept-7-yl]-, 1,1-dimethylethyl ester](/NewsImg/2024-01-03/6383987749077649741893529.jpg "Carbamic acid, [(7S)-5-(phenylmethyl)-5-azaspiro[2.4]hept-7-yl]-, 1,1-dimethylethyl ester")
