Reaction Steps

To a well-stirred mixture of methyl 3-methylbut-2-enoate (50.0 g, 438 mmol), 40% Triton B in MeOH (5 mL) and piperidine (4 mL) were added dropwise at 0° C., then methyl 3-mercaptopropanoate (50 g, 396 mmol) was added. After stirring for 24 h at 60° C., Et2O (500 mL) was added, and the organic phase washed thoroughly with 10% H2SO4 (150 mL), sat. NaHCO3 (150 mL), and brine (200 mL) successively, dried over Na2SO4 and evaporated under vacuum to give the title compound as a colorless oil (90.1 g, 97.23%).
