For clinical diagnosis, it is hoped that the MGMT expression level could be determined by a noninvasive method to understand the detailed biological properties of MGMT-specific tumors. We synthesized 11C-labeled O^6-[(3-methyl)benzyl]guanine ([11C]mMeBG) as a positron emission tomography probe. Thus, a mixed amine-protected stannyl precursor, N9-(tert-butoxycarbonyl)-O^6-[3-(tributylstannyl)benzyl]-N2-(trifluoroacetyl)guanine, was subjected to rapid C-[11C]methylation under [11C]CH3I/[Pd2(dba)3]/P(o-CH3C6H4)3/CuCl/K2CO3 in NMP, followed by quick deprotection with LiOH/H2O, giving [11C]mMeBG with total radioactivity of 1.34 GBq and \u226599% radiochemical and chemical purities.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/26868"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.bmcl.2017.03.045", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2017.
