I would like to reduce a ketone to a secondary alcohol with an
unprotected amine function in the molecule.  Those should the only
functional groups that would limit my choice of reducing agents. 
Suggestions? Pls suggest approximate conditions also.

Amine groups are normally not affected by the reduction agents, do you
have any specific reasons to worry?
Also, you need to tell more details about your system, if you want a
more specific  answer than the recipes from an organic chemistry
textbook, like "try lithium tetrahydridoaluminate in ethoxyethane" or
"sodium borohydride in ethanol".

Can you tell us what the molecule is?

eugene-123:

Sorry, structure is confidential.  But it is jus alky and aryl stuff.

Basic organic textbook may work, but I was concerned about the hydride
ions abstracting protons from the amine.  Maybe that's no problem. 
Maybe I just add an extra molar equivalent of hydride? Could you cite
a reference?

In 30 ml of heated methanol, dissolve 4.9 mmol of aminoketone and 29.4
mmol of cerium chloride heptahydrate. Cool the mixture to -20C and
while stirring
add 14.7 mmol of sodium borohydride by portions within 20-30 min.
After the mixture is stirred for 1h, slowly warm to room temperature,
stir for 5 h and boil for 2 h. Distill the solvent off, to the residue
add 30 ml of 2 N hydrochloric acid and extract the reaction product
into dichloromethane (2x15 ml). Wash the organic solution with 10 ml
of 20% aqueous ammonia, dry with sodium sulfate, and distill the
solvent off in a vacuum. Subject the residue to chromatography on a
column charged with 10 g of silica gel (eluent benzene). This will
obtain a mixture containing diastereomeric alcohols.
