A New Practical Route for the Manufacture of (4aR,10aR)-9-Methoxy-1-methyl-6-trimethylsilanyl- 1,2,3,4,4a,5,10,10a-octahydrobenzo[<i>g</i>]quinoline

Different synthetic routes to the enantiomerically pure octahydrobenzo[g]quinoline derivative JNZ092 were evaluated for their suitability to rapidly prepare a first clinical batch on a kilogram scale. On the basis of the experience of previous octahydrobenzo[g]quinoline projects a new linear synthesis of JNZ092 was established and scaled up successfully. The overall yield was increased by a factor
