Reaction Steps

4.9 g of N-methoxy-N-methylcarbamic chloride was added drop-by-drop (over 5 minutes) to a mixture of 6.6 g of 1D, 125 ml of THF and 5.2 g of N,N-diisopropyl-N-ethylamine, at -10° C. The mixture was stirred for 1 hour at 0° C., and then mixed with ice water. The resulting mixture was extracted with ether, the extract was dried (MgSO4) and the solvent was evaporated, to give 1-(2,3-dihydro-2-methylbenzofuran-7-yl)-4-methoxy-4-methylsemicarbazide (1E), as an amber syrup.
