実験手順

A solution of compound 37 (22 g, 0.042 mol) in methanol (100 mL) was treated with PTSA.H2O (0.80 g, 0.0042 mol) and stirred for 6 h at RT. The reaction mixture was concentrated under vacuum and the crude compound was used for next reaction (10.5 g, crude product). TLC: Chloroform/Methanol, 1:1, Rf=0.2
