Reaction Steps

50 g of absolute ethyl alcohol and 24.6 g (0.1 mol) of N-acetyl tryptophan (DL) were mixed in a 250-ml three-necked flask, yielding a rather thick paste. 6.5 g (0.107 M) of monoethanolamine was added; the mixture dissolved rapidly, after which the salt was observed to crystallise. The mixture was heated to 70° C. for 30 minutes and cooled to 20° C. The crystals (colourless) were thoroughly centrifuged, washed in ethyl ether and dried at 50° C.
