With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14618-45-2,3-(Trifluoroacetyl)indole,as a common compound, the synthetic route is as follows.
General procedure for preparation of XY; A solution of XInt01 (1 eq), K2CO3 (5 eq) and alkyl halides Y such as methyl iodide, ethyl iodide, n-propyl bromide, iso-propyl bromide, n-butyl bromide, isobutyl bromide (1.5 eq, 1 h) or O-t-butyldimethylsilyl-2-chloroethanol (10 eq, 24 h) or O-t-butyldimethylsilyl-2-chloropropanol in acetone was stirred and heated to reflux. After completion of the reaction (monitored by thin layer chromatography (TLC)), the mixture was concentrated in vacuo and the residue treated with dichloromethane. The insoluble impurities were removed by filtration and the filtrate was concentrated to afford compound XY (60-95% yield).; Example 6; N-(cyclopentylmethyl)-1-methyl-1H-indole-3-carboxamide; Synthesised according to the procedure disclosed in Example 1 where X is indole, Y is methyl iodide and Z is cyclopentylmethyl amine. Formula: C16H20N2O; Molecular Weight: 256.3; Mass/charge ratio: 256.2 (100.0%), 257.2 (18.3%), 258.2 (1.8%); Elemental analysis: C, 74.97; H, 7.86; N, 10.93; O, 6.24.
14618-45-2, 14618-45-2 3-(Trifluoroacetyl)indole 589126, aindole-building-block compound, is more and more widely used in various fields.
