Abstract:
The present invention relates to a pyrrolopyrimidine compound as TLR7 agonist, and particularly relates to a compound of formula (I) or a pharmaceutically acceptable salt thereof, a preparation process thereof, a pharmaceutical composition containing such compounds and use thereof for manufacturing a medicament against viral infection.

Claim (Index 17):
A compound of formula (I) or a pharmaceutically acceptable salt thereof wherein\n L 1  and L 2  are each independently selected from the group consisting of \u2014O\u2014 and \u2014CH 2 \u2014; \n R 1  is selected from the group consisting of C 1-10  alkyl, wherein the above C 1-10  alkyl is optionally substituted by one or more R 4 ; \n R 2  is selected from the group consisting of hydrogen, cyano and \u2014CONH 2 , wherein the above \u2014CONH 2  is optionally substituted by one or more R 4 ; \n B is selected from the group consisting of C 3-10  cyclohydrocarbyl, 3-10 membered heterocyclohydrocarbyl, aryl and heteroaryl; \n L 3  is selected from the group consisting of C 0-6  alkylene, wherein the above C 0-6  alkylene is optionally substituted by one or more R 4 ; \n R 3  is selected from the group consisting of hydrogen, amino, C 1-10  alkyl, C 3-10  cyclohydrocarbyl, 3-10 membered heterocyclohydrocarbyl, aryl and heteroaryl, wherein the above amino, C 1-10  alkyl, C 3-10  cyclohydrocarbyl, 3-10 membered heterocyclohydrocarbyl, aryl and heteroaryl are optionally substituted by one or more R 4 ; or \n R 3  and L 3  together with the adjacent atom at the ring B form a saturated or unsaturated 5-8 membered ring, the 5-8 membered ring is optionally substituted by one or more R 4 ; \n n is 0, 1, 2, 3, 4 or 5; \n R 4  is selected from the group consisting of halogen, \u2014R, \u2014OR and \u2550O; \n R is independently selected from the group consisting of H and C 1-8  alkyl; and \n when L 1  is \u2014CH 2 \u2014, R 3  is not H.
