After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
