Versuchsvorschrift

A mixture of 6-(4-(4-(azidomethyl)-4-methoxypiperidin-1-yl)furo[3,2-d]pyrimidin-2-ylamino)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (0.030 g, 0.063 mmol, prepared using C from tert-butyl 4-(azidomethyl)-4-methoxypiperidine-1-carboxylate [WO 2010/080864, Example 257], A with 2,4-dichlorofuro[3,2-d]pyrimidine [ArkPharm] and B with 6-amino-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one [ArkPharm]) and triphenylphosphine (0.025 g, 0.094 mmol) in THF (16 mL) and water (2 mL) was stirred at about 100° C. overnight. The organic phase was removed and diluted with water. The aqueous phase was neutralized with aqueous 2 N NaOH and extracted with EtOAc. The combined organic phase was washed with brine and dried over Na2SO4, filtered, concentrated under vacuum and purified by HPLC (Table 2, Method v) to afford 6-(4-(4-(aminomethyl)-4-methoxypiperidin-1-yl)furo[3,2-d]pyrimidin-2-ylamino)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (0.022 g, 76%). LC/MS (Table 2, method h) Rt=1.77 min.; MS m/z: 453 (M+H)+. Syk IC50=A
