Participants

Reaction Steps

To 8.1 g 3-Chloro-1-phenyl-isoquinoline-4-aldehyde in 150 ml methanol there are added portionwise 1.8 g sodium boron hydride at 0° C. The solution is stirred at room temperature for 4 hours and the solvent is removed in vacuo. The residue is stirred with water. Filtration of the resulting mixture gives 7.2 g 3-chloro-4-hydroxymethyl-1-phenyl-isoquinoline having a melting point from 175° to 182° C.
