Production method 2,6-dimethyl-4 (3H) -quinazolinone (I) N-alkylated with tert-pentanoyloxymethyl chloride and brominated with N-bromosuccinimide, To give 6- (bromomethyl) -2-methyl-3- [(tert-pentanoyloxy) methyl] -4 (3H) -quinazolinone (III). (m) is condensed with diethyl N- [5-methylaminothiophene-2-carbonyl] -L-glutamate, and the product V and sodium hydroxide aqueous solution are stirred and hydrolyzed at room temperature, The protecting group is then acidified to give the product.
