実験手順
380 mg (1.49 mmol) 5-Bromo-6-cyclopropylmethoxy-benzaldehyde (example XIX), 239 μL (4.47 mmol) nitromethane and 115 mg (1.49 mmol) ammonium acetate in 1.2 mL AcOH are stirred at 100° C. for 2 h. The reaction mixture is cooled to r.t. and quenched by the addition of 4 mL MeOH and 0.9 mL water. After stirring at r.t. for 1 h the precipitate is filtered off and dried at 40° C.
後処理
- customquenched by the addition of 4 mL MeOH and 0.9 mL water
- filtrationis filtered off
- customdried at 40° C.
