실험 절차
46.0 g of 1,2,3,4-tetrahydro-6-hydroxy-isoquinoline-hydrobromide are reacted with 85 ml of formamide for 1 hour at 140° C. with stirring. After cooling to 100° C., 216 ml of water are added, whereby the reaction product crystallizes. 34.0 g of 2-formyl-1,2,3,4-tetrahydro-6-hydroxy-isoquinoline are obtained. m.p. = 185.5° - 186° C. (ethanol).
