Patent ID: 7612114

Claim:
A compound represented by the following formula (I); wherein TZ represents a C1-C4 alkylene group or —CR f′ R g′ —CH 2 —O— wherein R f′ and R g′ independently represent a C1-C6 alkyl group; A represents a 5- to 14-membered heteroarylene group which may have a substituent or a C6-C14 arylene group which may have a substituent; Y represents —CH 2 —NR c — wherein R c represents a C1-C6 alkyl group which may have a substituent; ring G represents the following formula; R′ represents 1 to 4 substituents independently selected from a hydrogen and a C1-C6 alkoxy group; a partial structure in formula (I) represented by the following formula: is R″ represents a hydroxyl group that may be further protected by a protecting group or a C1-C6 alkoxy group which may have a substituent; and R a and R b are the same as or different from each other and each represents a hydrogen atom, a C1-C6 alkyl group which may have a substituent, or a C3-C8 cycloalkyl group which may have a substituent, or when R a and R b are bonded together, they may form, together with the nitrogen atom that is adjacent to R a and R b , a 4- to 10-membered single ring which may have a substituent; and L represents a single bond, or a salt thereof.
