Reaction Steps

At RT, 453 mg (1191 μmol) of HATU and 479 μl (2750 μmol) of N,N-diisopropylethylamine were added to a solution of 200 mg (916 μmol) of (+)-(2S)-cyclopentyl(4-methylphenyl)acetic acid in 1 ml of DMF. The mixture was stirred for 30 min. 249 mg (1008 μmol) of tert-butyl 1-(3-aminobenzyl)cyclopropanecarboxylate were then added. The reaction mixture was stirred overnight and then directly separated into its components by preparative HPLC. This gave 328 mg (80% of theory) of the title compound.
