Participants

Reaction Steps

[3,5-Bis-methoxymethoxy-4-(3-methyl-but-2-enyl)-phenyl]-methanol (2.0 g, 6.75 mmol) was dissolved in CH2Cl2 and placed in an ice bath. Triethylamine (1.2 ml, 8.92 mmol) was added and stirred until the reaction solution was at 0° C., followed by the dropwise addition of mesylate chloride (900 ul, 8.92 mmol). After stirring in the ice bath for 1 hour, the reaction was quenched with water, extracted with EtOAc, washed with brine, dried with MgSO4, filtered and evaporated yielding methanesulfonic acid 3,5-bis-methoxymethoxy-4-(3-methyl-but-2-enyl)-benzyl ester as a yellow oil. 1H NMR (CDCl3, 300 MHz) δ (ppm): 6.82 (s, 2H), 5.20 (t, 1H), 5.16 (s, 4H), 4.13 (s, 2H), 3.48 (s, 6H), 3.39 (d, 2H) 2.96 (s, 3H), 1.78 (s, 3H), 1.65 (s, 3H). MS (ESI) m/z: 375 (M+H)+, 397 (M+Na)+.
