Yield:-
Reaction Conditions:
with water;acetic acid in ethanol at 20; for 0.333333 h;
Steps:
1.5
Step 5: 4-Amino-3-formyl-benzoic acid methyl ester (Compound 7); [0222] Compound 6 (0.95g, 4.2 mmol) was dissolved at room temperature in 15 mL of a solvent mixture composed of EtOH-acetic acid-water 2: 2: 1. The strongly colored yellow solution became pale yellow in 5 minutes. The mixture was let stand for an additional 15 minutes before it was evaporated to dryness and further dried in high vacuum overnight to get Compound 7 as a yellow powder. [0223] MS: 180.05 (M+H+) ; H -NMR (CDC13) : 8 (ppm) 9.88 (s, 1H, CHO), 8.23 (d, 1H, J=2. 1HZ, AR-H2), 7.96-7. 91 (dd, 1H, J=8. 7Hz and 2. 1Hz,Ar-H6), 6.64 (d, 1H, J=8.4Hz, Ar-H5), 3. 88 (s, 1H, CH3).
