Reaction Steps

To a solution of 3-mercapto-2-methylpropanoic acid (2.4 g.) and freshly distillled 2,3-dihydro-4H-pyrane (1.9 g.) in benzene (60 ml.), boron trifluoride etherate (2.8 g.) is added. After two hours, potassium carbonate (4 g.) is added, the mixture is stirred and filtered. The filtrate is concentrated to dryness to yield 3-(tetrahydropyran-2-ylthio)-2-methylpropanoic acid.
