Versuchsvorschrift
A mixture of 62 (2.8 g, 0.009 mol) and 1,1,1-triethoxy-ethane (5.2 mL, 0.028 mol) were heated for 5 hours. The reaction mixture was poured into water, filtered, washed with water yielding compound 63 (55%). After recrystallization from EtOH, the material was used in next step without further purification.
