Reaction Steps

To a solution of phenyl(vinylsulfonyl)amine (141 mg, 0.77 mmol) and DIEA (0.47 mL, 4.9 mmol) in EtOH (7.5 mL) was added (2R)-1-(2-methylbenzothiazol-5-yloxy)-3-piperazin-1-ylpropan-2-ol (470 mg, 1.5 mmol, crude). The solution was heated for 2 hours at 85° C. on a J-Kem™ block. Upon cooling, the reaction mixture was concentrated to an oil and purified via flash column chromatography (4:1 EtOAc/MeOH) to afford [(2-{4-[(2R)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl]piperazinyl}ethyl)sulfonyl]phenylamine.
