70% | With hydrazine hydrate In methanol for 48h; | Preparation of hydrazide: A typical procedure 1 General procedure: A solution of methyl 4-tert-butylbenzoate (5.15 g, 26.8 mmol) and hydrazine monohydrate (1.50 ml, 30.0 mmol) in MeOH (15 mL) was stirred for 2 d. After the removal of the solvent in vacuo, the residue was recrystallized from MeOH to give 4-tert-butylbenzohydrazide (1b) (2.94 g, 15.3 mmol, 57%) as a colorless crystal. 1 H-NMR (300 MHz, DMSO-d 6 ): δ 9.68 (s, 1H), 7.75 (d, J = 8.5 Hz, 2H), 7.45 (d, J = 8.5 Hz, 2H), 4.44 (s, 2H), 1.28 (s, 9H) ppm. |

63% | With 1H-imidazole at 20℃; for 24h; | N-Formylation of aminoalcohol: A general procedure General procedure: To a solution of 5 (1.0 mmol) in DMF (1.0 mL), TBSOTf (2.0 mmol) and imidazole (1.0 mmol) were added at room temperature. After stirring for 24 h, the volatiles were evacuated, and the residue was directly chromatographed (eluent: dichloromethane:methanol, 20:1, v/v) to obtain 6. |
