Procedure

1-[2-(acetylthiomethyl)-5-oxo-6-methylheptanoyl]-L-proline (1.5 g.) is dissolved in cold methanol (10 ml.) and sodium borohydride (0.12 g.) is added. After two hours the reaction mixture is diluted with water (100 ml.) acidified with concentrated hydrochloric acid and extracted with ethyl acetate. The organic layer is dried and concentrated to dryness in vacuo to give 1-[2-(acetylthiomethyl)-5-hydroxy-6-methylheptanoyl]-L-proline.
