AIBN (1.5 g) was dissolved in trimethylolpropane monoallyl ether (497 g, 2.86 mol). This solution was slowly added, under nitrogen with stirring, to thiolactic acid (300 g, 2.83 mol) at such a rate that the temperature of the exothermal reaction was kept at 80° C. When the addition was completed, the temperature was raised to 90° C. and kept at 90° C. for 1 h. The product had 1H-NMR (CDCl3): δ 1.11 (t, 3H, CH3CH2), 1.53 (q, 2H, CH3CH2), 2.00-2.20 (m, 2H, CH2CH2CH2), 2.98-3.06 (m, 2H, 3.65-4.02 (m, 9H); and is soluble in methanol and toluene, not soluble in hexane.
