Reductive methylation of secondary amines containing reducible, hydrolyzable and sterically hindered groups
Davis, Bruce A.,Durden, David A.
, p. 3353 - 3362 (2000)
Aliphatic secondary amines, including those that are sterically hindered, undergo reductive methylation under mild conditions in high yield using formaldehyde and sodium phosphite solution without reducing or hydrolyzing ethynyl, ester or cyano groups.
