Versuchsvorschrift
2-(hydroxymethyl)-5-(4-methoxybenzyloxy)-4H-pyran-4-one (Intermediate 63, 6.44 g, 24.56 mmol) and ammonia (7N in MeOH) (59.6 ml, 417.45 mmol) were combined in a pressure reactor vessel and heated at 90° C. for 5 hours. The reaction mixture was cooled overnight then concentrated. The solid was suspended in water then collected by filtration. The title compound was obtained as a brown solid (3.48 g, 54%).
