Reaction Steps

0.182 g (1.00 mmol) of biphenyl-4-carbaldehyde and 0.224 g (1.20 mmol) tert-butyl piperazine-1-carboxylate were dissolved in 10 mL dry DCM. 0.35 mL (3.0 mmol) of trimethylorthoformate and 0.21 mL (1.50 mmol) triethylamine were then added to the reaction mixture at room temperature for 1 hr. The reaction was quenched with a solution of NaHCO3 and diluted with EtOAc. The layers were separated and the aqueous solution extracted with EtOAc 2×. The organic solution was dried over Na2SO4, filtered and concentrated in vacuo to give 0.35 g (100%) of 51 which was used as is for the next reaction.
