in tetrahydrofuran at -70; for 1 h;

Steps:

Preparation of A49
To a solution of 44 (100 mg, 0.9 rnmol) in THF (2 mL) is added MgMeBr (1 M, 1.1 mL, 1.1 mmoi) dropwise at --70 °C. After stirring for 1 hour, EtOH (1 rnL) is added at 0 °C and then the mixture is acidified with 2 M HC1 to pH 6. The mixture is then extracted with EA(i0 mL >c 2). The combined organic layers are dried over anhydrous sodium sulfate, filtered, concentrated, and purified by silica gel column chromatography (MeOH:DCM = 1:50) to give A49 as a colorless oil (80 mg, 70% yield).
