Recently it was discovered that the alkylation of ethyl JV-hydroxy-carbamate under alkaline conditions, particularly in a DMF medium at 60°C in the presence of sodium bicarbonate, leads to the ultimate formation of O-alkylated hydroxylamines. On the other hand, at 80-85°C, the direct alkylation without the presence of a base ultimately leads to N-alkylhydrox-ylamines (see Table I) [59]. The reaction of ethylazidoformate with an alcohol, while perhaps hazardous, may have some merit (Eqs. 31-33). The overall yield, based on ethyl chloroformate, is said to be on the order of 60%.

Yield:17508-17-7 98%
Reaction Conditions:
with hydrazine hydrate in dichloromethane at 0; for 4 h;
Steps:
Preparation of Compound 1-2
Preparation of Compound 1-2 2- (2,4-nitrophenoxy) isoindoline-1,3-dione 17.74g (53.88m) and then hydrazine mono-hydrate in yujihan state to 0 dissolved in dichloromethane 350 7.6 (157.33m after the addition of ) was stirred for 4 hours. When the reaction was completed, the reaction mixture poured into a 1N HCl at 0 stirred and the resulting solid was then filter. Filter the solids are washed with MeCN and the filtrate extracted with MC and the organic layer to obtain the desired compound 1-2 10.50g (98%) and dried over MgSO4
