실험 절차
(R)-5-tert-butoxy-2-isopropoxy-7-oxiranyl-benzothiazole (145 g, 471.7 mmol) and 2-(4-butoxy-phenyl)-1,1-dimethyl-ethylamine (114.8 g, 518.9 mmol) were dissolved in DMSO (850 ml). The reaction mixture was heated to 80° C. and stirred for 27 h. The mixture was then cooled to 25° C. and added to a stirred mixture of water (1500 ml) and TBME (1500 ml). The aqueous layer was separated and extracted with TBME (1000 ml). The combined organic layers were sequentially washed with water (1500 ml) and brine (1000 ml), dried with anhydrous Na2SO4. After concentration, the residue was purified by column chromatography (eluting with 10% of EtOAc in n-heptane to 33% of EtOAc in n-heptane). Solid product (R)-1-(5-tert-butoxy-2-isopropoxybenzo[d]thiazol-7-yl)-2-(1-(4-butoxyphenyl)-2-methylpropan-2-ylamino)ethanol was obtained (140 g) as off-white solid.
