求翻译:The solution was stirred with cooling in ice for 1 h and then filtered. The filter cake was washed with icecold MTBE (2 · 20 mL) and then filter dried at rt for 1 h. The filter cake was then washed with aqueous sulfuric acid (50 mM, 3 · 50 mL) and water (3 · 50 mL), after which it was filter dried at rt to give the fir是什么意思? 待解决

解答引起了与冷却在1个h的冰然后被过滤了。滤饼洗涤了与冰冷的MTBE (2·20 mL)然后过滤烘干在1个h.的rt。滤饼然后洗涤了与含水硫酸(50 mM, 3·50 mL)和水(3·50 mL),在后它是过滤器被烘干在rt给第一片庄稼(R) - 2作为一种白色水晶固体:22.3 g, >99%有力(高性能液体色谱), 68%出产量, >99.8% ee;

解答引起了以冷却在冰为1 h然后被过滤了。 滤饼洗涤了与冰冷的MTBE (2 · 20机器语言) 然后过滤烘干在rt为1 h。 滤饼然后洗涤了与含水硫酸 (50毫米, 3 · 50机器语言) 和水 (3 · 50机器语言),在之后它是过滤器被烘干在rt给第一片庄稼 (R) -2作为一种白色水晶固体: 22.3 g, >99%有力 (高性能液体色谱), 68%出产量, >99.8% ee;

解决方案是与冷却在冰上 1 h 搅拌,然后进行筛选。滤饼被冲走与 icecold 甲基叔丁基醚 (2 · 20 毫升),然后筛选器在室温下干燥 1 h。滤饼被然后冲水硫酸 (50 毫米,3 · 50 毫升) 和水 (3 · 50 毫升) 后它是, 筛选器干在室温下给的 (R)-2 为白色结晶固体第一作物: 22.3 g > 99%效能 (HPLC) 68%yield,>99.8%ee ;
