Safety of 2,3-Dioxoindoline-5-sulfonyl chloride

A solution of rpml21 (0.211 g, 0.861 mmol) and morpholine (0.187 g, 2.139 mmol, 2.5 eq), in anhydrous DCM (7 ml) and anhydrous chloroform (1 ml) was stirred for 3h at room temperature under Ar. The yellow precipitate was collected by filtration and dried under vacuum. The crude product was used in the next step without further purification.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 132898-96-5, its application will become more common.
