Reaction Conditions

Reaction Steps

A mixture of the title compound of Step C (0.387 g, 1.2 mmol) and N-chlorosuccinimide (0.168 g, 1.26 mmol) in dimethylformamide (6 mL) was heated at 80° C. for 4 h. After completion of the reaction, the mixture was poured into a mixture of ether (25 mL) and water (10 mL). The organic phase was separated, dried (MgSO4) and the solvent was removed on a rotary evaporator. Flash chromatography of the resulting residue afforded 0.4 g of the title compound of Step D. 1H NMR (CDCl3, 400 MHz): δ7.23 (d,2H), 7.03 (d,1H), 6.74 (d,2H), 4.93 (s,2H), 3.84 (s,2H), 3.75 (s,3H).
