Reaction Steps

A mixture of 4-bromo-1-methyl-2-nitro-benzene (f-1) (0.01134 mol) and paraformaldehyde (0.009 mol) in DMSO (5 ml) and Triton-B (035 ml) was stirred at 50° C. for 2 hours, then cooled to room temperature and purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH 98.5/1.5; 35-70 μm). The pure fractions were collected and the solvent was evaporated. Yield: 1.18 g of 2-(4-Bromo-2-nitro-phenyl)-ethanol (f-2) (42%).
