Selective reduction of the carboxyl group to the alcohol can be achieved in 94% yield using Benzyl­triethyl­ammonium borohydride, B24952, in combination with TMS chloride. Esters are unaffected under these conditions: Synth. Commun., 20, 907 (1990). See also, J. Chem. Soc., Chem. Commun., 903 (1989).
