Reaction Steps

The process is performed according to the protocol described in Example 2 (step 2.1). Starting with 1 g (4.81 mmol) of 4-bromoisoquinoline, 0.683 g (5.29 mmol) of 2-(4-piperidyl)ethanol, 1.11 g (11.50 mmol) of sodium tert-butoxide, 0.090 g (0.144 mmol) of BINAP and 0.044 g (0.048 mmol) of tris(dibenzylideneacetone)dipalladium, and after chromatography on silica gel, eluting with a 97/3 and then 95/5 mixture of dichloromethane and methanol, 0.810 g of product is obtained in the form of a viscous green liquid.
