The solvent was evaporated and the residue was washed with water and extracted with DCM. The organic phase was dried over sodium sulphate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography eluting with DCM to give after precipitation from ether, the title compound as a white solid (180 mg, 57%). HRMS calculated for C19H19FN4O3 (M+H)+371.1519. found: 371.1500, Rt: 2.78 min. MP: 119.7° C.
