Procedure

A mixture of tert-butyl (1S,4S)-5-{[(1R,4S)-4-amino-1-ethylcyclopent-2-en-1-yl]carbonyl}-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (2.12 g, 6.32 mmol) and 5% palladium on carbon in methanol (35 ml) was stirred at room temperature under 48 psi of hydrogen for 21 hours. The reaction was filtered through celite and the filter cake washed with methanol. The filtrate and washings were concentrated under reduced pressure to give tert-butyl (1S,4S)-5-{[(1S,3R)-3-amino-1-ethylcyclopentyl]carbonyl}-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate as a brown oil/foam (2.46 g, theoretical yield 2.13 g) which was used without further purification in the next step.

Workup

  1. filtrationThe reaction was filtered through celite
  2. washthe filter cake washed with methanol
