Reaction Steps

To a solution of compound (7) (540 mg, 2 mmol, Preparation 2) and 4-amino-2-methyl-butan-1-ol (230 mg, 2 mmol) in DMSO (20 mL) was added Et3N (404 mg, 4 mmol). The reaction mixture was stirred at 110° C. overnight. The reaction mixture was diluted with water, extracted with EtOAc (50 mL×3). The combined organic extracts were washed with water (30 mL) and brine (30 mL), dried over Na2SO4 and filtered. The filtrate was evaporated in vacuo and the residue was purified by flash column chromatography (EtOAc: Petrol ether=3:1) on silica gel to give (36). (557 mg, 1.6 mmol, yield 80%).
