Abstract: The present disclosure relates to a new, simple, two step synthesis of Indolmycin and its derivatives of formula (I), in 4-5 hours. Formula (I) wherein said process comprising the step of: 10 (a) reacting indole derivative with methyl magnesium bromide in a suitable solvent at a temperature in the range of 0-30° C. followed by adding ethyl epoxy butanone in a suitable solvent at ?20° C. for a period of 1-2 hrs and maintaining the obtained reaction mixture for 1 hr at ?20° C. to obtain a compound; and (b) passing the compound obtained at step a), base and N-methylated quinidine 15 through solid-solid continuous flow reactor for 1 minute to obtain the compound of formula (I).

Abstract: The present invention provides a polysaccharide supported fluorinating agents which can be used in fluorination reactions. The invention particularly describes a new bacterial cellulose supported tetra-n-butyl ammonium fluoride complex [NBu4(Bac-Cell-OH)F] which is stable and non-hygroscopic. The invention further relates to a process for fluorination using the [NBu4(Bac-Cell-OH)F] complex.
