Yield: 86.8%

Reaction Conditions:

with methanol;barium(II) hydroxide at 20; for 48 h;

Steps:

1 Step 1: Synthesis of Intermediate 01-103-2
To a stirred solution of 01-103-1 (3 g, 8.76 mmol) in MeOH (15 mL) at RT was added slowly Ba(OH)2 (0.75 g, 4.4 mmol). The resulting mixture was stirred at RT. After 48 h, the reaction mixture was quenched with ice water, acidified with 1.5 M HCl, and extracted with EtOAc. The combined organic extract was washed with water, brine, dried over Na2SO4, and then evaporated to yield crude 01-103-2. Purification by column chromatography (10% EtOAc in petroleum ether) afforded 01-103-2 as an off-white solid (2.5 g, 86.8%).
