实验过程

0.06 ml of isopropyl isocyanate was added to a solution of 0.2 g of the compound obtained in step 2.4 in 1.2 ml of DCM, at 0° C. The medium was stirred for 2 h at 0° C. then hydrolysed with 5 ml of water and diluted with 10 ml of DCM. The organic phase was washed twice with a saturated NaHCO3 solution then with a saturated NaCl solution. After drying over MgSO4, the organic phase was concentrated then purified by flash chromatography to produce 0.16 g of the expected product.
