Reaction Steps
A solution of BBr3 (0.07 mol) in 15 ml CH2Cl2 is added at 0° to a solution of 0.014 mol 5-methoxy-benzothiophene-3-carboxaldehyde in 80 ml CH2Cl2. After 4 hours 2 N Na2CO3 is added until pH=7. The organic solvent is evaporated and the suspension is filtered. The solid is washed with water to yield crude title compound which is recrystallized from CH3OH/H2O. M.p.=200°.
