Procedure
Potassium t-butoxide (0.22 g, 1.9 mmol) was added to 5 mL of t-butanol in a 25 mL round bottom flask. The (4aR)-(10bR)-10b-methyl-8-phenylthio-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]-quinolin-3-one, (0.183 g, 0.566 mmol) was added followed by methyl iodide while cooling briefly in an ice bath. The mixture was allowed to stir at room temperature for 18 h before diluting with ethyl acetate and filtering to remove inorganics. Filtrate was concentrated in vacuo to give a oil which was triturated in hexane/diethyl ether to facilitate crystallization. Recrystallization from ethyl acetate/hexane gave 0.90 g of white crystals: mp 109°-112°; FD MS 337 M+; Calcd for C21H23N1O1S1.
