Versuchsvorschrift

To a mixture of (V) (5.0 g, 22.8 mmol) and ethyl acetoacetate (2.97 g 22.8 mmol) was slowly added PCl3 (3.13 g, 22.8 mmol). The mixture was warmed to 50° C. for 1.5 h, poured into ice water (150 ml), and the resulting precipitate was collected on a sintered glass funnel and recrystallized from EtOH to yield (VI) (2.29 g, 41%) as white crystals, mp 208-211° C. (lit. 208-209° C.), TLC CHCl3/MeOH 9:1.
