1030377-21-9, (S)-1-Boc-2-(Hydroxymethyl)piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A mixture of (S)-tert-butyl 2-(hydroxymethyl)piperazine-l -carboxylate (850.9 mg, 3.93 mmol) and 2-(tert-butoxymethyl)oxirane (850 mg, 6.46 mmol) in ethanol (10 mL) was heated at 120 C for 30 min using microwave. The mixture was concentrated to dryness. The residue was purified with flash column chromatography on silica gel using 1-10% methanol in dichloromethane to afford a oil as the product in quantitative yield. 1H NMR (500 MHz, Chloroform-^ delta 4.09 (s, lH), 3.84 (m, 3H), 3.38 (dt, J= 9.0, 3.7 Hz, l H), 3.28 (m, 3H), 3.04 (dd, J = 24.2, 1 1.7 Hz, 1H), 2.88 – 2.80 (m, 2H), 2.48 – 2.32 (m, 3H), 2.26 – 2.21 (m, 1H), 2.13-2.08 (m, 1H), 1.44 (s, 9H), 1.17 (d, 9H). MS for ^Eta34Nu205: 347.2 (MH+).

1030377-21-9, 1030377-21-9 (S)-1-Boc-2-(Hydroxymethyl)piperazine 22884145, apiperazines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1030377-21-9,(S)-1-Boc-2-(Hydroxymethyl)piperazine,as a common compound, the synthetic route is as follows.

To a solution of (S)-l-Boc-2-hydroxymethylpiperazine (1.0 g, 4.62 mmol) in DCE (92.47 ml, 4.624 mmol) was added formaldehyde (3.474 ml, 46.24 mmol) (37% in water) followed by sodium triacetoxyborohydnde (4.9 g, 23.12 mmol). The mixture was stirred vigorously at room temperature for 2.5hours. The mixture was treated with saturated sodium bicarbonate (30 mL), stirred for 10 min then extracted with DCM (3 x 10 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated. ES+APCI MS m/z 231.1 [M+H]+., 1030377-21-9

The synthetic route of 1030377-21-9 has been constantly updated, and we look forward to future research findings.
