With sodium carbonate; In water; at 20℃; for 3h; | General procedure: The hydroxy- or methoxycarbonitrile derivative (1 eq) was added to the cysteine derivative (1.05 eq) and sodium carbonate (3 eq) in 5 ml water. The mixture was stirred at room temperature for three hours before addition of dilute HCl (1 M) to pH ? 3.5 - 4.0. The product was isolated by extraction with diethyl ether, washed by water, followed by evaporation |

86% | D-Cysteine hydrochloride monohydrate (30.0 mg, 0.171 mmcl, 1.04 eq) and 2-cyano-6-hydroxy- benzothiazole (29.0 mg, 0.163 mmol, 1 eq) were dissolved in 2:1 MeOH:H20 (1 mL). The resultingsolution was allowed to stir at room temperature for 5 mm under a nitrogen atmosphere, after which potassium carbonate (23.0 mg, 0.164 mmol 1.01 eq) was added. The resulting bright yellow-green solution was allowed to stir for an additional 20 mm, at room temperature, while maintaining the inert atmosphere. Upon consumption of <strong>[939-69-5]2-cyano-6-hydroxybenzothiazole</strong>, as evidenced by TLC analysis, the methanol was removed in vacuo and the remaining aqueoussolution cooled to 0 °C and acidified to pH 3 with 3 M HCI. The aqueous layer was then extracted with EtOAc (5 x 10 mL) and the combined organ ics were dried over Na2SO4, filtered, concentrated in vacuo and purified with column chromatography 3:6:1 DCM:EtOAc:MeOH to provide D-luciferin as a pale yellow solid (39.0 mg, 86 percent).
