Abstract
1444552 N-Disubstituted-2-aminoethanols BEECHAM GROUP Ltd 5 Dec 1973 [5 Dec 1972] 56002/72 Heading C2C Compounds of formula wherein R is a n-propyl or i-butyl group, are obtained by reducing an oxazolidine derivative of formula wherein either (1) R 1 and R 2 are both C 2 H 5 , (2) R 1 =CH 3 and R 2 =n-C 3 H 7 , (3) R 1 =i-C 3 H 7 and R 2 = C 2 H 5 or (4) R 1 = CH 3 and R 2 = i-C 4 H 9 . Preferred reducing systems are hydrogen plus a metal catalyst (e.g. Ni), complex hydrides (e.g. LiAlH 4 or NaBH 4 ) or cyclohexene in the presence of a palladium-on-charcoal catalyst. The oxazolidine starting materials are prepared by reacting a 2-aminoethanol N-substituted by group R 2 with the corresponding aldehyde, R 1 -CHO.
