Downstream synthetic route of 3612-20-2

The synthetic route of 3612-20-2 has been constantly updated, and we look forward to future research findings.

3612-20-2, 1-Benzylpiperidin-4-one is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A solution of 294.14 g 1-benzylpiperidin-4-one in 2.1 L methanol was added to a solution of 448 g ammonium carbonate in 2.1 L hot water. The yellow turbid reaction mixture was cooled with an ice bath. A solution of 77 g sodium cyanide in 200 ml water was added dropwise over 10 min (exothermic.). After the addition the ice bath was removed and the reaction mixture was stirred at ambient temperature for 3 days. The resulting precipitate was filtered, washed with water (3x) and dried in a vacuum oven at 50C to obtain the intermediate 1.38.Yield: quantitative, 3612-20-2

The synthetic route of 3612-20-2 has been constantly updated, and we look forward to future research findings.
