“…The acetone derivative of 6-3ß, 17/3-dihydroxy-17a-aminomethylandrostene is hydrolyzed by cold dilute acetic acid into its components (62). In a number of cases stable picrates have been obtained; some, however, can be prepared only in ether, and even recrystallization from alcohol causes hydrolysis and formation of the picrate of the corresponding aminoalcohol (58,65,75,113). In several instances, on the other hand, stable hydrochlorides of the condensation products have been described; viz., the hydrochlorides of the condensation products of aminotrimethylolmethane with cyclohexanone and benzaldehyde (92), of 2-amino-lindanol and various aromatic aldehydes (61), and of the bicyclic compound (91):…”
