Procedure
The process is performed as described in Example 4 (step 4.1). Starting with 1.52 g (8.39 mmol) of 1-chloro-6-fluoroisoquinoline and 1.20 g (9.23 mmol) of 2-(4-piperidyl)ethanol, and after chromatography on silica gel, eluting with a 95/5/0.5 mixture of dichloromethane, methanol and 28% aqueous ammonia, 0.90 g of pure product is obtained in the form of a yellow paste.
Workup
- washafter chromatography on silica gel, eluting with a 95/5/0.5 mixture of dichloromethane, methanol and 28% aqueous ammonia
