Procedure

A solution of D5 (1.90 mmol, 0.62 g) in 40 mL acetonitrile/water (1/1) was refluxed for 5 hours. The reaction mixture was evaporated in vacuo. The crude product was purified by flash silicagel chromatography (DCM/MeOH=95/5) yielding 0.34 g of a yellow oil (66%). 1H-NMR (400 MHz, CDCl3, 300K): δ=1.46 (9H, s), 1.88 (1H, m), 2.26 (1H, m), 3.50 (8H, m), 6.70 (1H, br d, 34.8 Hz); MS (ES) C13H20N2O4 requires: 268. found: 269.4 [M+H]+.
