Capecitabine is an important anticancer drug whose synthesis comprises late-stage carbamoylation and ester hydrolysis. Herein we report the use of the Schotten–Baumann reaction in order to perform these transformation in one pot both in batch and under continuous flow. In batch, capecitabine was obtained in 82% yield in 5 h, while under continuous flow it was obtained in 81% yield in 30 min. This one-pot
