    Abstract: PROBLEM TO BE SOLVED: To obtain a new compound useful as an intermediate for producing a water-soluble camptothecin derivative used for treating tumors. SOLUTION: A compound of formula I [(n) is 1 or 2; R1, R2 are each H, a 1-6C alkyl or the like, or R1 is H, a 1-6C alkyl or the like and R2 is a group of the formula; COR3, or R1 and R2 are bonded to each other together with a nitrogen atom bonded thereto to form a saturated three to seven-membered heterogeneous group; R3 is H, a 1-6C alkyl or the like; Y is O, S or the like], for example, 2'-amino-4',5'-methylenedioxy-2-trifluoroacetamidoacetophenone. The compound of formula I is obtained by reacting a compound of formula III (X is a halogen) (for example, 2'-amino-4',5'-methylenedioxy-2- chloroacetophenone) with a compound of the formula: HNR1R2 (for example, trifluoroacetamine) in the presence of a base in an aprotic polar solvent such as acetonitrile.
