Reaction Conditions:

with titanium tetrachloride in dichloromethane at 0 - 20; for 4 h;Rieche Formylation;

Steps:

2.1 1. Rieche Formylation reaction (preparation of compound of formula 7)

General procedure: Anhydrous CH2Cl2 (75 mL) Dichloromethyl methyl ether (dichloromethyl methyl ether) (40 mmol) and TiCl4 (48 mmol) ofThe solution was stirred magnetically in a was treated at 0 the aryl bromide solution in dry CH2Cl2 (25 mL).The reaction mixture was stirred at room temperature for 4 hours.Followed by the addition of cold 5% HCl aqueous solution (20 mL) at 0 , stirring was continued for 15 minutes. The organic layer was then separated and the aqueous solution was extracted with CH2Cl2 (3 x 20 mL). The extract was washed with 5% aqueous NaHCO3 (80 mL) and brine (80 mL) After drying (MgSO4)Concentration under reduced pressure gave bromobenzaldehyde (compound of formula 7).
