Yield:606-25-7 96.7%
Reaction Conditions:
with ammonium hydroxide in acetone at 0;
Steps:
1 Preparation of 1-naphthalenesulfonamide (Compound 2)
1-naphthalenesulfonyl chloride (5 g, 21.9 mmol) was added to a 1 L round bottom flask containing 200 ml of acetone, stirred, In the ice bath drop 240ml 0°C of ammonia, dripping finished, the thin layer tracking test reaction, the reaction is completed, Vacuum distillation of organic solvents and ammonia decomposition of ammonia, precipitation of solid, filtration, vacuum drying, To give 1-naphthalenesulfonamide (4.35 g, yield 96.7%). The compound was used in the next step without further purification. The experimental data are as follows:
