2-甲基苯并呋喃-3-甲醛

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-Methylbenzofuran-3-carbaldehyde (0.51 g, 3.18 mmol) was dissolved in anhydrous ethanol (25 mL). Sulfamide (1.5 g, 16 mmol) was added and the mixture was heated to reflux for 4 days. The mixture was cooled to room temperature. Sodium borohydride (0.132 g, 3.50 mmol) was added and the mixture was stirred at room temperature for 24 hours. The reaction was diluted with water (100 mL) and extracted with DCM (3×75 mL). The extracts were concentrated and suspended in a minimal amount of DCM and filtered to yield the title compound as a white solid. the mixture was heated to reflux for 4 days extracted with DCM (3×75 mL) The extracts were concentrated filtered
