Hydrazine hydrate (1:1) → HCID 57808442, compound

Participants

Reaction Steps

The mono-methyl ester 5 (10 mg, 0.033 mmol) was dissolved in 3.5 mL anhydrous ethanol (dried over 4 Å molecular sieves). Hydrazine hydrate was added (55 μL, 1.65 mmol, 53 mg), and the reaction was stirred for 5.5 hours at room temperature under an atmosphere of nitrogen. The volatiles were evaporated under reduced pressure, and the product oil was triturated three times with ca. 3 mL diethyl ether. The bright yellow oil was dried under high vacuum to produce a 10 mg (quant.) of a pale yellow solid. MS: (ESI-TOF) MH+ expected: 306.1924, found: 306.1923.
