Reaction Conditions

Reaction Steps

The above product was mixed with DIPEA (1.2 eq) in THF and stirred at 0° C. for 10 minutes, to the reaction was added ethyl chloroformate (1 eq) slowly and further stirred for 1.5 hours from 0° C. to RT. To the reaction cooled at 0° C. was added NaBH4 (1.5 eq) slowly followed by MeOH (2 eq) and stirred for 2 hours from 0° C. to RT. The reaction was diluted with EtOAc, water and extracted with EtOAc three times. The combined organic layer was washed with water, brine and dried. The solution was evaporated and purified with silica gel column to give methyl 1-(hydroxymethyl)cyclo-propanecarboxylate (2.5 g).
