HCID 14864563-(dimethylamino)-1-(1H-indol-3-yl)prop-2-en-1-one

Procedure

A mixture of 3.18 g of 3-acetylindole and 5.17 ml. (4.36 g) of tert-butoxybis(dimethylamino)methane was heated on a steam bath for 4 hours. The cooled reaction mixture was triturated with n-hexanes and gave a semisolid. The solvent was removed in vacuo and the material was triturated with dichloromethane giving 3.08 g of the desired compound as a tan crystalline solid, mp 239°-245° C.,
