Reaction Steps

1.93 g (10.0 mmol) 6-chloropyrimidine-4-carboxylic acid chloride, 1.80 g (10.9 mmol) 4-methyl-3H-benzothiazol-2-one and 7.33 g (55.0 mmol) aluminium trichloride were combined and heated to 130° C. for 3 h with stirring. The mixture was combined with ice water and EtOAc, the flakes formed were suction filtered and the phases were separated. The aqueous phase was extracted with EtOAc. The organic phases were combined, dried on sodium sulphate, filtered and the filtrate was evaporated down i. vac. The residue was triturated with DIPE, the precipitate was suction filtered and dried.
