摘要：
The present invention provides processes for the preparation of baricitinib of Formula I and an intermediate of Formula V. The present invention also provides the use of the intermediate of Formula V for the preparation of baricitinib. The present invention provides an environmentally friendly cost effective and industrially advantageous process for the preparation of baricitinib of Formula I. The process of the present invention involves the use of an environmentally benign heterogeneous catalyst such as a zeolite. The use of a zeolite as a catalyst is beneficial for large scale synthesis owing to its inexpensive nature ease of handling ease of isolation of the product high reaction yields and recyclability.
