The present disclosure relates to a process for the preparation of lumateperone tosylate intermediate. The process comprises the conversion of benzyl 6-bromo-5-(2-(methylamino)-2-oxoethyl)-1,3,4,5-tetrahydro-2H-pyrido[4,3-b]indole-2-carboxylate to lumateperone tosylate intermediate in a comparatively high yield and high purity. The process of the present disclosure is simple, employs inexpensive reagents and is environment friendly. |
