There is provided a process for the preparation of aromatic amines of Formula (1):
where R
x
is optionally substituted aryl and R
y
is optionally substituted hydrocarbyl, which comprises:
(a) reducing a compound of Formula (2):
to give a compound of Formula (3):
then, (b) reacting a compound of Formula (3) with a leaving group donor, to give a compound of Formula (4);
and, (c) reacting a compound of Formula (4) with ammonia to give the compound of Formula (1).

A process for the preparation of a compound of Formula (1) wherein Ar represents an optionally substituted hydrocarbyl or an optionally substituted heterocyclyl group comprising an aromatic moiety; and R
1
and R
2
each independently represent an optionally substituted hydrocarbyl or an optionally substituted heterocyclyl group; said process comprising: a) reducing a compound of Formula (2) to form a compound of Formula (3): b) activating the compound of Formula (3) to form a compound of Formula (4): wherein OX represents a leaving group; and c) coupling the compound of Formula (4) to a compound of Formula (5): to form a compound of Formula (1). A stereoselective reduction of ketones to alcohols is also disclosed.
