20. 2 (5 mL) and ethanol (15 mL); yield 45%. Note that, to avoid the formation of oil, crystallization should be carried out at 0°C using ethanol containing a small amount of MeCN or PhCN as precipitating agent. Furthermore, compounds 1 are air-sensitive and must be handled under an inert atmosphere.
