After cooling at room temperature it was diluted with EtAcO (20 mL), washed with water, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was purified by a silica SPE cartridge (10 g) eluting with DCM/MeOH from 99/1 to 96/4 to give the title compound as a colourless oil (143 mg).
