(2-formyl-6-methoxyphenyl) benzenesulfonate

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: o-Vanillin (350 g, 2.3 mols) was added to a solution of NaOH (166 g, 4.15 mols) in 2 1 water. Benzenesulfonyl chloride (485 g, 2.74 mols) was added to the slurry at 20°-25° C. over 1 hour. The solid which formed was collected on a filter, washed with 2 1 water, and redissolved in CH2Cl2. That solution was dried (MgSO4) and evaporated to a slurry. The solid was collected on a filter, the filtrate was further evaporated and filtered. The solid was washed with MeOH and dried in vacuo to afford the desired product, (511 g, 81.4%), mp 120°-122° C. The solid which formed was collected on a filter washed with 2 1 water redissolved in CH2Cl2 That solution was dried (MgSO4) evaporated to a slurry The solid was collected on a filter the filtrate was further evaporated filtered The solid was washed with MeOH dried in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
