Reaction Steps

To a solution of 6-[3-butyl-5-hydroxymethyl-isoxazol-4-ylmethoxy]-nicotinic acid methyl ester (100 mg, 0.31 mmol) in toluene (1 mL) was added isopropylamine (55 mg, 0.93 mmol) and 1,5,7-triazabicyclo[4.4.0]dec-5-ene (26 mg, 0.19 mmol). The reaction mixture was stirred for 3.5 days at 50° C. A further portion of isopropylamine was added and the reaction was heated at 50° C. for an additional 3.5 days. Dichloromethane (40 mL) was added and the reaction mixture was concentrated in vacuo onto silica gel and purified by chromatography (silica, dichloromethane:methanol 1:0 to 9:1) to afford the title compound (18 mg, 17%) as a colorless oil. MS: m/e=348.3 [M+H]+.
