Cyclo-condensation of N-methyl-2-bromoaniline with chlorocarbonylsulfenyl chloride (CCSC) promoted by PhNMe 2 and AlCl 3 , afforded N-methyl-2-bromo-2(3H)-benzothiazol-2-one in good yield. Miyaura-Ishiyama cross-coupling of this brominated 2(3H)-benzothiazol-2-one with bis(pinacolato)diborone [(pin) 2 B 2 ] produced a novel N-methyl-4-(pin)B-2(3H)-benzothiazol-2-one (3) using (pin) 2 B 2 in the presence of the PdCl 2 (PPh 3 ) 2 catalyst. The obtained 4-(pin)B compound is regarded as a new entrydoi:10.3390/m976 fatcat:qnwlqgy6o5eyxbmclhrvuynhiy
