Participants

Reaction Steps

To a 0° C. solution of (1R,2R)-2-amino-1-(2-methoxyphenyl)-3-(pyrrolidin-1-yl)propan-1-ol (0.1 g, 0.40 mmol) (compound 6) in THF (5 ml) was added Hunig's Base (0.07 g, 0.52 mmol), followed by the dropwise addition of octanoyl chloride (0.07 g, 0.40 mmol). The resulting mixture was allowed to stir overnight at room temperature, diluted with EtOAc, and washed with satd. aq. NaHCO3, satd. aq. NaCl, and dried over MgSO4. Purified by flash silica chromatography (MeOH/CH2Cl2) to give a yellow oil (0.03 g, 0.09 mmol, 22% yield). HPLC purity 93% (tR=5.3 min) NMR (500 MHz, CDCl3) δ 7.4 (m, 1H), 7.2-7.3 (m, 1H), 6.9-7.0 (m, 1H), 6.8-6.9 (m, 1H), 6.0-6.1 (m, 1H), 5.3 (d, 1H), 4.2-4.3 (m, 1H), 3.8 (s, 3H), 2.9-3.0 (m, 3H), 2.5-2.7 (m, 4H), 2.0-2.1 (m, 2H), 1.7-1.8 (m, 4H), 1.9-2.0 (m, 2H), 1.2-1.4 (m, 6H), 0.8-0.9 (t, 3H).
