NEW MATERIAL:A compound shown by the formula I [R1 is higher alkyl; R2 and R3 are linked to form group shown by the formula II (R4 is carboxy which may be protected) or R2 is H and R3 is group shown by the formula III (R5 and R6 are H, phenylalkyl; n is 0, or 1), etc.] and its salt. EXAMPLE:N-(15-Methylhexadecanoyl)-L-phenylalanine. USE:A drug having fibrinolysis promoting action and anti-inflammatory action. PREPARATION:A compound shown by the formula R1-COOH of formula V or a reactive derivative (e.g., dialkyl phosphate, phenyl phosphate, etc.) at its carboxyl group or its salt (e.g., triethylamine salt, etc.) is reacted with a compound shown by the formula IV or its reactive derivative at its amino group or its salt to give a compound shown by the formula I or its salt (e.g., sodium or potassium salt).
