The invention provides new processes for making and purifying amino acid compounds, which are useful in the preparation of AKT inhibitors used in the treatment of diseases such as cancer, including the compound -2–1–7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopentadpyrimidin-4-yl)piperazin-1-yl)-3-propan-1-one. The exemplary antenna system includes a first transformer connected to the second bent portion and configured to invert current of the second bent portion relative to current received from the first portion. Each of the multiple memory arrays may store a respective vertical error correction code specific to data of that memory array. As a result, the silicon oxycarbide isolation insulator advantageously provides reduced noise and signal crosstalk between circuit nodes, reduced power consumption, faster circuit operation, and minimizes the risk of potential timing faults. The guide unit includes a hinge assembly for pivoting the display at a predetermined angle, an arm assembly having first and second ends respectively connected to the hinge assembly and the receiving portion, and a pivot control unit providing a pivotal force of the arm assembly with respect to the receiving portion. A light source is disposed in the gap between the reflection sheet and the film structure so as to provide light.
