Procedure
N-Boc-D-homophenylalanine Quinoline-3-amide (2.6 g, 6.42 mmol, procedure 1A) was treated with trifluoroacetic acid (15 mL) at 25° C. for 1 hr. The solution was concentrated to dryness and treated with diethyl ether (10 mL). The solid was filtered and dried. It was dissolved in water (180 mL) and neutralized to pH=7.5 with saturated solution of sodium bicarbonate. The mixture was stirred for 1 hr and the solid was filtered and dried giving the title compound (1.30 g) as white solid.
