Procedure

A solution of N-(2-chloro-6-methylbenzoyl)-4-[(2,6-dichlorophenyl)carbonyl]amino]-L-phenylalanine (0.15 g) in 1.0 N NaOH (0.3 mL) was applied to a 2×20 cm open column of C-18 reversed phase silica gel (40-63 μM, RP Silica Gel60, as supplied by EM Separations, Cat. 10167) eluting with water, then with 40-50% methanol in water to give N-(2-chloro-6-methylbenzoyl)-4-[(2,6-dichlorophenyl)carbonyl]amino]-L-phenylalanine sodium salt (147 mg) as an amorphous white solid after lyophilization.
