求翻译: To a stirred solution of 2,3-dihydro-3,3-dimethyl-5-hydroxy-2- piperidino-benzofuran in dry pyridine at 5-10oC was added methanesulphonyl chloride over 1 hour. The mixture was stirred for a further 5 hours at about 10oC, then poured into water. The precipitated gum was washed with water, then triturated with ethanol 是什么意思?![]() ![]() To a stirred solution of 2,3-dihydro-3,3-dimethyl-5-hydroxy-2- piperidino-benzofuran in dry pyridine at 5-10oC was added methanesulphonyl chloride over 1 hour.
