A mixture of 3-methoxythiophenol (2.20 g, 15.7 mmol), [(1S,2R,4aS,8aS)-2-hydroxy-2,5,5,8a-tetramethyl-decahydronaphthalen-1-yl]methyl methanesulfonate (12) (5.0 g, 15 mmol), and Cs2CO3 (15.30 g, 47.16 mmol) in CH3CN (600 mL) was stirred at room temperature for 1 h, then refluxed for 24 h. After cooling, the mixture was concentrated and purified by column chromatography on silica gel (Hexanes/EtOAc, 10:1 to 6:1) to give (1R,2R,4aS,8aS)-1-{[(3-methoxyphenyl)sulfanyl]methyl}-2,5,5,8a-tetramethyl-decahydronaphthalen-2-ol (13-1) (4.03 g, 71%) as a yellow oil.
