Reaction Steps

A solution of 3-bromo-1,1-diphenyl-2-propanone (0.5 g) in tetrahydrofuran (10 ml) was added to a mixture of (2-methoxy-benzyl)amine (1.13 ml) and N,N-diisopropylethylamine (0.602 ml) in tetrahydrofuran (12 ml) over 0.5 hour at room temperature. After being stirred at room temperature for 1.5 hours, the mixture was concentrated under reduced pressure to half volume and the resulting mixture was poured into ice-water (10 ml) and extracted with ethyl acetate (10 ml×2). The extract was washed with brine, dried over magnesium sulfate and evaporated under reduced pressure to give 3-[(2-methoxybenzyl)amino]-1,1-diphenylpropan-2-one (483 mg) as a colourless syrup.
