(Chimimanie: "Nitrile reduction using Cobalt Chloride and NaBH4", Methods Discourse). I used 10 mmol RCN (2.56g; but it was mixture of isomers -Post 299551 (https://www.thevespiary.org/talk/index.php?topic=6905.msg29955100#msg29955100)
(karel: "Chloromethylation", Chemistry Discourse), note 4) and after amine isolation recycled 2.11g RCN back. So I did not further investigate this reaction , but used AlH3 in THF (see JACS 1968, 2927-2938), which gave 90% yield of amine.
