実験手順

2.4 g lithium aluminium hydride is added very slowly to 10.6 g 3-benzoyl-2-chloropyridine in 100 ml anhydrous pyridine. After stirring for 2 hrs. at room temperature, the solvent is distilled in vacuo, the residue is added to 5% aqueous HCl and extracted with ether. Working as usual there is obtained 4.5 g of a product, identical with that obtained as in (a).
