Participants

Reaction Steps

130 mg (ca. 0.65 mmol) crude 4-[(2-Fluoro-ethyl)-methyl-amino]-2-hydroxy-benzaldehyde and 202 mg (1.5 eq.) benzothiazol-2-yl-acetic acid methyl ester are dissolved in 3 mL acetonitrile and 6 mL benzene, treated with 0.14 mL (2 eq.) piperidine and heated to reflux for 45 minutes. After cooling to room temperature, the crude product is extracted with AcOEt/isopropanol 9:1 and saline, dried over sodium sulfate and evaporated. The crude product is dissolved in 20 mL methanol, and slowly concentrated down to 10 mL at 50° C. The orange crystals are filtered and dried under high vacuum to yield 110 mg (48%) desired product.
