Participants

Reaction Steps

Under inert condition a 500 mL round bottom flask with a magnetic stirrer was charged with 6.87 g (30 mmol) of 1-tert.-butyloxycarbonyl-piperidine-4-carboxylic acid, 110 mg (0.09 mmol) DMAP and 11.5 g (60 mmol) 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide, hydrochloride and 150 mL DCM. To the light yellow solution 3.25 g (45 mmol) 2-methyl-2-propen-1-ol was added. The reaction mixture was stirred over night at room temperature. The mixture was concentrated under vacuum, isolute-HM-N was added and evaporated to dryness. The residue was purified over silica eluting with heptane and ethyl acetate to yield after evaporation of the product containing fractions 7.3 g (86%) of the title compound as colourless oil. MS ISP (m/e): 306.2 [(M+H)+].
