Cyclohexyl isothiocyanate → HCID 178431653, compound

Participants

Reaction Steps

A solution of 150 mg of 2-hydroxy-2-methyl-1-phenylpropane-1-sulfonamide and 97 mg of cyclohexyl isothiocyanate in 1.5 ml of NMP was admixed with 0.20 ml of a 2 N solution of sodium bis(trimethylsilyl)amide in THF. After stirring for 20 minutes, 71 mg of N-bromosuccinimide were added and the mixture was stirred at room temperature for a further 15 minutes. The reaction solution was admixed with 50 ml of water and extracted twice with 50 ml of ethyl acetate. The combined organic phases were dried over Na2SO4 and concentrated by rotary evaporation. The residue was purified in a purification laboratory by means of preparative HPLC, and the product-containing fractions were freed of the organic solvent under reduced pressure. The aqueous residue was extracted three times with dichloromethane, and the combined organic phases were dried using a phase separator cartridge (Chromabond® PTS) and concentrated by rotary evaporation. The residue was dissolved in a mixture of acetonitrile and water and lyophilized. This gave the product (46 mg) with a molecular weight of 336.4 g/mol (C17H24N2O3S); MS (ESI): m/e=337 (M+H+).
