The present invention relates to a pyrimidine compound of the formula (I):wherein R1 represents a hydrogen atom, halogen atom or C1-C4 alkyl; R2 represents C3-C7 alkynyloxy; R3 represents a hydrogen atom, halogen atom or C1-C3 alkyl; X represents C4-C7 polymethylene, in which a CH?2#191-CH?2#191 may be replaced with a CH=CH, optionally substituted with at least one substituent selected from the group consisting of halogen atoms, trifluoromethyl and C1-C4 alkyls. This pyrimidine compound has an excellent activity of controlling pests.

Upon photolysis in methylene chloride at −78 °C, different N-chlorolactams underwent a novelringcontraction to the corresponding carbamoyl chlorides, which were converted to the methyl carbamates. The rearrangement is 100% stereoselective, occurring with retention of configuration at the migrating carbon center. The yields of isolated carbamates ranged from 40% to 57%, the other product being the
