With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.86542-94-1,1-(Piperidin-4-yl)propan-1-one,as a common compound, the synthetic route is as follows.
86542-94-1, Preparation ofl-(l-(4-( trifluoromethoxy )benzyl )piperidin-4-yl)propan-l -one 4v[00227] 4-Trifluoromethoxy benzyl bromide (1.52g, 5.94 mmol) was first added to a solution of l-(piperidin-4-yl)propan-l-one (0.7g, 4.95 mmol) in DMF (20mL) followed by K2C03 (1.4g, 9.9 mmol) and heated overnight at 120C. The DMF was removed under vacuum and the crude mixture was partitioned between water (10 mL) in EtOAc (30 mL). The organic layer was washed with brine and concentrated. Purification by flash column chromatography afforded the desired product. (Colorless oil, 50%); 1H NMR (400MHz, CDC13), deltaEta 7.33 (d, 2H, J = 8.3 Hz, Ar), 7.15 (d, 2H, J = 8.3 Hz, Ar), 3.48 (s, 2H, NCH2Ar), 2.88 (dd, 2H, J = 8.6 Hz, 3.1 Hz, CH2), 2.47 (q, 2H, J = 7.3 Hz, CH2CO), 2.32 (tt, 1H, J = 11.4 Hz, 3.9 Hz, CH), 2.09-1.96 (m, 2H, CH2), 1.80 (d, 2H, J = 11.3 Hz, CH2), 1.74-1.62 (m, 2H, CH2), 1.04 (t, 3H, J = 7.3 Hz, CH3); MS (ES+), [M + H] + (100), 316.2, HRMS calculated for 316.1524 Ci6H2iN02F3, found 316.1525.
The synthetic route of 86542-94-1 has been constantly updated, and we look forward to future research findings.
