실험 절차

The process is performed as described in Example 2 (step 2.1). Starting with 2.50 g (15.28 mmol) of 1-chloroisoquinoline, 1.94 g (136.6 mmol) of 4-piperidylmethanol, 3.53 g (36.67 mmol) of sodium tert-butoxide, 0.285 g (0.46 mmol) of BINAP and 0.140 g (0.15 mmol) of tris(dibenzylideneacetone)dipalladium, and after chromatography on silica gel, eluting with a 98/2/0.2 and then 95/5/0.5 mixture of dichloromethane, methanol and 28% aqueous ammonia, 2.40 g of pure product are obtained in the form of a viscous orange oil.
