refluxed at 90 oC for 3 h. Once the reaction was complete by TLC, it was diluted with EA and filtered through a bed of celite. The filtrate was concentrated in vacuum. The residue was purified by silica chromatography (25% EA:hexane) to afford desired product as a crystalline solid. Tert-butyl3-chloro-5-methyl-6-(thiophen-2-yl)-5H-pyrrolo[2,3-b] pyrazin-2-ylcarbamate (4a). Pale yellow solid, yield: 71.8%, mp: 136.2-137 oC. 1H NMR (500 MHz, CDCl3) δ 7.51 – 7.47 (m, 1H), 7.38 – 7.34 (m, 1H), 7.19 (d, J =

The major peaks for experimental 2-chloro-2-methylbutane was sp3 C-H stretch 2939-2977 cm-1 and C-Cl 798.29 cm-1. The major shifts in H NMR was δ1.55, s, 6H; 1.73, q, 2H; and 1.03, t, 3H. IR and h NMR indicted little to no contamination. Cyclohexanol was used to form cyclohexene with calculated yield of 11.0% (0.17 g, 2.07 mmol). The major IR peaks were 3373.23 cm-1 O-H stretch, 3022.05 =C-H stretch, 2935.76-2837.09 cm-1 C-H stretch, and 1652.61 cm-1 –C=C- stretch with two unknown peaks were

12 and m H I ST,A = 19.39 ± 0.26 mag, respectively. Conversely, using aperture photometry for measuring the magnitudes of the NIR > 3σ detections is not possible in this case, since their stellar profiles are not fully recovered. Alternatively, their J , H , and K S magnitudes can be estimated by taking the ratio of the added NIR peak fluxes of the two guide stars (i.e. G.S.1 and G.S.2) to the peak fluxes of the

Responsibility): (prezi, n.d.)H&M is one of the world 's most ethical organisation. H&M takes after sustainability and environmental policy. As indicated by H&M, "we have a duty towards everybody who add to our prosperity, including the individuals who are not employees of H&M." (The H&M Way, n.d.) That is the reason this organisation continually work with providers to build up a long term, sustainable, social and environmental standard in the factories that makes H&M items. Their duties in environmental

Elemental analysis (C, H, and N) and Mass spectra were performed at the Micro analytical Unit of Cairo University using a Vario III CHN analyzer and DI analysis Shimadzu QP-2010 plus mass spectrometer, respectively. The chemical reagents used are Aldrich and BDH. Synthesis of
