The reaction mixture was then irradiated with microwave for 40 min at 150\u00a1\u00e3 C. After the reaction was done, the reaction mixture was cooled to room temperature, filtered through a celite pad and the filtrate was concentrated under reduced pressure. The residue was purified in a silica gel column eluting with dichloromethane\/methanol (1percent to 5percent gradient) to afford 1-(2-hydroxyethyl)-1H-pyrazole-4-carbaldehyde (650 mg, 89percent) as yellow solid.
