How is 1,2,5-Oxadiazol-3-ylmethanol (CAS: 79552-35-5) typically synthesized?

1,2,5-Oxadiazol-3-ylmethanol is commonly synthesized via the reaction of 3-formyl-1,2,5-oxadiazole with methanol. This synthesis typically employs a catalytic amount of a suitable acid like sulfuric acid and proceeds under mild conditions. The yield is around 85%, and the reaction is selective for the methanol addition to the 3-formyl group.
