Summary: | To provide a process for preparing an AKT inhibitor.SOLUTION: The present disclosure relates to a process for preparing a (cyclopentyl[d]pyrimidin-4-yl)piperazine compound, and more particularly relates to a process for preparing (R)-4-(5-methyl-7-oxo-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazine and an N-protected derivative thereof, which can be used as intermediates in the synthesis of ipatasertib (i.e., (S)-2-(4-chlorophenyl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(isopropylamino)-propan-1-one). The present disclosure further relates to various compounds which are intermediates used in these processes.SELECTED DRAWING: None
