Reaction Steps
To a solution of Intermediate 9 (1.02 g, 2.2 mmol) in methanol (20 mL) was added PPTS (56 mg). After heating to 55° C. for 24 h, the reaction mixture was cooled to RT and concentrated. Purification by MPLC (30% ethyl acetate in hexanes) gave 621 mg of Intermediate 16 as a colorless oil.
