YieldReaction ConditionsOperation in experiment
100% A solution of 1(R)-tert-butoxycarbonylamino-2(S)-vinyl-cyclopropanecarboxylic acid (4.45 g, 19.6 mmol) and 1,1'-carbonyldiimidazole (3.97 g, 24.5 mmol) in dry THF (60 mL) was heated to boiling under reflux for 90 min. Upon cooling to rt, the mixture was treated sequentially with the product from Example 100, Step 2 (5.17 g, 24.5 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (6.26 g, 41.1 mmol). The resulting mixture was stirred at rt for 72h, and was then concentrated in vacuo to a viscous brown oil. The residue was dissolved in ethyl acetate (300 mL) and was washed with 1N HCl (3.x.75 mL) and then with brine (75 mL). The organic was dried over anhydrous magnesium sulfate, filtered, and concentrated. Purification by flash silica gel chromatography (DCM, then 1percent MeOH in DCM) gave 8.4 g (quantitative yield) of the desired product as an off-white solid: MS m/z 443 ((M+Na)+).
