tert-Butanol → HCID 86615466, compound

Participants

Reaction Steps

To a stirred and cooled solution of commercially available chlorosulfonyl isocyanate (0.215 mL, 2.47 mmol) in dichloromethane (5 mL) was added tert-butanol (0.232 mL, 2.47 mmol) and the mixture was stirred at 0° C. for 30 min. Then 4-{3-[6-methyl-4-(4-trifluoromethyl-phenyl)-pyridin-2-yl]-phenyl}-thiazol-2-ylamine (example 342) (0.100 g, 0.243 mmol) and triethyl amine (0.42 mL, 2.96 mmol) were added and the mixture was stirred at 23° C. for 0.5 h. Diluted with DCM, washed with sat. NaHCO3-sol. and water, dried the organic layer over Na2SO4. Removal of the solvent in vacuum left a crude product which was purified by silica gel column chromatography with heptane/EtOAc/THF, followed by trituration with diethyl ether/heptane to give the title compound as a white solid (0.060 g, 42%). MS (ISP) 591.3 [(M+H)+]; mp 152° C. (dec.).
