Yield:5463-29-6 76%
Reaction Conditions:
with acetic acid at 130; for 16 h;
Steps:
B.20.1 Step 1
A mixture of R-3 (6.0 g, 26.55 mmol) and R-4 (8.2 g, 79.65 mmol) in acetic acid (25 mL) is stirred at 130oC for 16h. The reaction mixture is cooled and concentrated under reduced pressure to remove acetic acid. The residue is diluted with water (200 mL), neutralized with saturated aqueous NaHCO3to pH=7-8 and filtered. The filtrate is acidified with conc. aqueous HCl to pH=1-2, filtered and the solid is dried to afford I-1 (5.4 g, 76%).
