tert-butyl 4-((2S)-8-(1S,4S)-2-oxa-5-azabicyclo[2.2.1]hept-5-yl-6-oxo-2-trifluoromethyl-3,4-dihydro-2H,6H-pyrimido[1,2-a]pyrimidin-1-ylmethyl)piperidine-1-carboxylate 788 mg (2.84 mmol) of tert-butyl 4-bromomethylpiperidine-1-carboxylate and 425 mg (2.84 mmol) of sodium iodide are added to a solution of 690 mg (2.18 mmol) of (8S)-2-(1S,4S)-2-oxa-5-azabicyclo[2.2.1]hept-5-yl-8-trifluoromethyl-6,7,8,9-tetrahydropyrimido[1,2-a]pyrimidin-4-one and 2.13 g (6.54 mmol) of cesium carbonate in 10 mL of acetonitrile. The reaction mixture is heated in a Biotage microwave reactor at 100 C. for 3 hours. The reaction medium is evaporated to dryness and the residue is taken up in EtOAc and washed with water and with saturated NaCl. The organic phase is dried over magnesium sulfate and evaporated to dryness. The residue is purified by chromatography on silica gel (eluent: 95/5 DCM/MeOH) to give 510 mg of tert-butyl 4-((2S)-8-(1S,4S)-2-oxa-5-azabicyclo[2.2.1]hept-5-yl-6-oxo-2-trifluoromethyl-3,4-dihydro-2H,6H-pyrimido[1,2-a]pyrimidin-1-ylmethyl)piperidine-1-carboxylate, the characteristics of which are as follows: LC/MS (method G): ESI+ [M+H]+: m/z 514 tr (min)=2.45 1H NMR (300 MHz, delta in ppm, DMSO-d6): 0.93-1.03 (m, 1H), 1.11-1.32 (m, 3H), 1.38 (s, 9H), 1.44-1.64 (m, 2H), 1.76-1.91 (m, 2H), 1.99-2.39 (m, 3H), 2.78-3.32 (m, 5H), 3.60 (m, 1H), 3.71 (m, 1H), 3.86-3.99 (m, 2H), 4.06-4.19 (m, 2H), 4.48-4.92 (m, 3H).
