N-Tosyl-5-bromo-4,7-diazaindole Chemical Properties,Usage,Production

Uses

N-Tosyl-5-bromo-4,7-diazaindole is an intermediate of upadacitinib, known asupadacitinib intermediate, or upadacitinib impurity 2. As an inhibitor of Janus kinase1, upadacitinib selectively inhibits Janus kinase1 for immune system diseases such as psoriatic arthritis, rheumatoid arthritis, and Crohn's disease[1-3].

Uses

either carboxyl or hydroxyl functional. The carboxyl functional are used for hybrids with epoxy resin for indoor applications and for outdoor applications. They are cured with b-hydroxyalkylamides. Hydroxyfunctional polyesters are cured with internal or external blocked isocyanates. The liquid polyesters are intended for highquality 90 % peroxide at<100 C[ 

Preparation

A solution of anhydrous DMF (272 mL) dissolved with 2-bromo-5H-pyrrolo[2,3-b]pyrazine (78.0 g, 394 mmol) was configured. The temperature is maintained at 0-5 °C (within which the subsequent reaction has been maintained), and the solution was droppedly added to the sodium (12.8 g, 532 mmol) anhydrous DMF (543 mL) suspension in the stirred state within 60 minutes. The solution turned brown and the reaction solution was stirred for about 30 min. Then, within 60 minutes, anhydrous DMF (272 mL) dissolved with p-toluenesulfonyl chloride (94.0 g, 492 mmol) was added. After stirring the mixed solution for about 1 h, it was heated to ambient temperature and stirred for about 18 h. Slowly pour the reaction mixture into ice water (6 L) and added 2.5 N NaOH in water (50.0 mL, 125 mmol). Filter the sediment to collect and stirred 3 times with cold water (200 mL). Finally, the collected products were filtered and dried to a constant weight in a vacuum oven at about 55 °C to obtain N-Tosyl-5-bromo-4,7-diazaindole (134.6 g, 97%).

Safety

N-Tosyl-5-bromo-4,7-diazaindole can cause skin irritation, severe eye irritation, and possibly respiratory irritation.
