Reaction Steps

To a solution of 0.40 g of (6S)-3-Butyl-3-hydroxy-6-tert-butyldimethoxy-siloxymethyl-9,10-dimethoxy-1,3,4,6,7,11b-hexahydro-pyrido[2,1-a]isoquinolin-2-one in 13 ml of THF at 0° C. was slowly added a solution of 1.78 ml of tetrabutylammonium fluoride (1M in THF). The reaction mixture was stirred for 2 hours keeping the temperature between 0-5° C. The reaction mixture was poured into ice cooled water (49 ml) and then extracted two times with 30 ml of ethyl acetate. The organic extracts were dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was then purified by chromatography (silica gel, hexane/ethyl acetate 0-70%) to give 0.30 g of (6S)-3-Butyl-6-hydroxymethyl-9,10-dimethoxy-1,3,4,6,7,11b-hexahydro-pyrido[2,1-a]isoquinolin-2-one, MS (ISP) 348.3 (M+H)+.
