YieldReaction ConditionsOperation in experiment
77% General procedure: N-Pivaloyl-4-chloroaniline (33, 595 mg, 2.81 mmol) was dissolved in THF (50 ml), and the solution was added sec-butyl lithium c-hexane, n-hexane solution (0.99 M, 5.96 ml, 6.18 mmol) at -78 C, and then stirred at 0 C for 2 h. The mixture was added 2-chloro-3-fluoro-benzaldehyde (490 mg, 3.09 mmol) at the same temperature for 30 min. The reaction mixture was poured saturated with NH4Claq and AcOEt. The organic layer was washed with brine and dried over Na2SO4. The solvent was removed under reduced pressure, and the residue was purified by column chromatography (n-hexane/AcOEt = 9:1) to give the title compound (676 mg, 65%) as light yellow oil.

YieldReaction ConditionsOperation in experiment
0.332 g A solution of 2,3-dihydrobenzo[b][l,4]dioxine-5-carbaldehyde (0.500 g, 3.04 mmol) in acetone (10 mL) was stirred at 0-5°C and aqueous solution of sulphamic acid (0.455 g, 4.5 mmol) was added. The reaction mass was stirred for 20 min. Then aqueous solution of sodium chlorite (0.421 g, 4.5 mmol) was added and the reaction was further continued at RT for 18 h. After completion of reaction, reaction mixture was concentrated under reduced pressure and reaction mass was quenched with water. Solid obtained was filtered off and vacuum dried to afford 0.332 g of desired product. 1H NMR (DMSO-de): delta 4.27 (s, 4H), 6.84 (t, J = 7.2 Hz, 1H), 7.02 (d, J = 7.8 Hz, 1H), 7.20 (d, J= 7.5 Hz, 1H), 12.5 (bs, 1H); MS [M+H]+: 181.12.
