The reaction mixture is cooled to room temperature and treated with saturated aqueous NaHCO3 until the pH of the reaction mixture is pH 7 and is then concentrated under reduced pressure to dryness. The residue is diluted with ethyl acetate and water, poured into a separatory funnel and the layers separated. The ethyl acetate layer is washed with brine, dried (Na2SO4) and concentrated under reduced pressure. The red solid residue is triturated with diethyl ether to yield a light brown solid and a red filtrate. The solid is collected and washed with diethyl ether to yield 0.20 g (91%) of the pure desired product as a light brown solid. MS ESI (+) m/z 300 (M+1) detected.

Procedure:
A 250 mL RBF was charged with 2-bromo-7-methoxy-9H-xanthen-9-one (10.20 g, 33.4 mmol) and 100 mL dry THF. The mixture was stirred for 10 min at RT and the resulting suspension was placed in an ice-methanol bath for another 10 min. Ethylmagnesium bromide, 1.0 M in THF (43.5 mL, 43.5 mmol) was added to the mixture dropwise. After 30 min, the mixture was carefully quenched with saturated aqueous ammonium chloride (100 mL) at 0° C. and diluted with EtOAc. The organic layer was washed with brine, dried with sodium sulfate, and concentrated in vacuo. The crude material was dissolved in 100 mL of chloroform, treated with pyridine 4-methylbenzenesulfonate (0.115 g, 0.669 mmol), and heated to reflux for 4 hr then 50° C. overnight. The mixture was cooled to RT, diluted with DCM, and washed with saturated sodium bicarbonate and brine. The organic fraction was dried over sodium sulfate and concentrated in vacuo.

Procedure:
Into a flask equipped with a stirrer, a distilling column, a nitrogen inlet, a heating jacket, and a thermometer were charged 486 g of triethyl orthoacetate, 408 g of pentaerythritol, 300 g of diethylene glycol dimethyl ether, and 0.9 g of PTSA. The mixture was gradually heated to 170° C. over a period of 5 hours. During this time 490 g of distillate were obtained. The distillate contained mostly ethanol and small amounts of diethylene glycol dimethyl ether. The temperature was lowered to 100° C., and the remaining diethylene glycol dimethyl ether was distilled off under reduced pressure (30 mbar). The residue was subjected to vacuum distillation. The fraction having a boiling temperature of 126-130° C. at a pressure of 4 mbar yielded 426 g of oil. This oil solidified to a clear solid having a melting point of 99° C. and had the following structure
