Procedure

1192 mg (6.2 mmol) of EDC, 578 μl (4.1 mmol) of triethylamine, 345 mg (2.8 mmol) of DMAP, and 328 mg (2.1 mmol) of 1-naphthylmethanol were added at RT to a solution of 500 mg (1.89 mmol) of N-Boc-L-phenylalanine in 25 ml dichlormethane. The reaction composition was stirred overnight, then diluted with 50 ml Dichlormethane and successively washed in a solution of 10% of aqueous citric acid, water, and saturated saline. The organic phase was dried over magnesium sulphate and then evaporated, and the residue purified with preparative HPLC. The yield was 501 mg (66% o. th.) of the title compound.
