Reaction Steps
To a stirred yellow solution of VII (371.8 mg, 1.089 mmol) in anhydrous THF (10 mL) was added 2-phenoxyethylamine (165 mg, 157 μL, 1.1×1.089 mmol) and then, dropwise, triethylamine (121 mg, 168 μL, 1.1×1.089 mmol). The solution was stirred for 1.5 hours at room temperature. The colorless solution was then diluted with CH2Cl2 and washed with 1N HCl, distilled water, and saturated NaCl. The organic layer was dried over anhydrous MgSO4, filtered, and concentrated. The crude product was purified by column chromatography on silica gel using hexanes/ethyl acetate (1:1, v/v) to yield 260.6 mg (67%) of a 11 as a clear light yellow oil: Rf=0.39 (hexanes/ethyl acetate, 1:1, v/v); 1HNMR (CDCl3) δ 7.26 (td, 3J=8.0 Hz, 4J=1.1 Hz, 2H), 6.98 (d, 3J=8.0 Hz, 1H), 6.96 (m, 1H), 6.94 (d, 4J=1.0 Hz, 1H), 6.92 (dd, 3J=8.7 Hz, 1H), 6.86 (d, 3J=8.1 Hz, 2H), 5.21 (bs, 1H, NH), 5.06 (s, 2H), 4.03 (t, 3J=5.0 Hz, 2H), 3.80 (s, 3H), 3.59 (q, 3J=5.2 Hz, 2H, NCH2) and 2.29 (s, 3H). Exact mass (EST) calculated for C19H22NO6 [M+H]=360.1442. found 360.1443.
