Procedure
This aldehyde was prepared from acetal 13 at a scale and under conditions identical to those employed for the preparation N-(2-oxoethyl)-5-(dimethylamino)naphthalene-1-sulfonamide from acetal 11. N-(4-Oxobutyl)-5-(dimethylamino)naphthalene-1-sulfonamide was obtained as a light green foam, the total amount of which was used without further purification in the preparation of 14.
