95% | With N-ethyl-N,N-diisopropylamine; In N,N-dimethyl-formamide; | Step 4-Synthesis of q: To a cool (0 C.) solution of <strong>[1260088-72-9]2,4-dichloro-7,7-dimethyl-5,7-dihydrofuro[3,4-d]pyrimidine</strong> (p) (2.53 g, 11.5 mmol), DIPEA (4.8 mL, 28 mmol) and DMF (15 mL) was added (3S)-3-methylmorpholine (1.42 g, 14 mmol), the solution was allowed to warm slowly over 15 h. The solution was poured into sat. NH4Cl (100 mL) and extracted with ether (3×50 mL). The combined org. phases were washed with brine (1×25 mL), dried (MgSO4), filtered, and concentrated to afford 3.18 g (95%) of (S)-2-chloro-7,7-dimethyl-4-(3-methylmorpholino)-5,7-dihydrofuro[3,4-d]pyrimidine (q) as a colorless solid: 1H NMR (400 MHz, CDCl3) delta 5.10 (d, J=11.3 Hz, 1H), 5.05 (d, J=11.3 Hz, 1H), 4.11 (s, 1H), 3.85-4.00 (m, 2H), 3.84-3.66 (m, 2H), 3.55 (ddd, J=11.9, 11.9, 2.8 Hz, 1H), 3.39 (ddd, J=13.0, 13.0, 3.2 Hz, 1H), 1.47 (s, 3H), 1.46 (s, 3H), 1.36 (d, J=6.8 Hz, 3H); LC-MS: m/z=+284 (M+H)+. |
