Procedure

Powdered sodium-borohydride (0.33 g, 8.6 mmol) was added in portions at 0° C., to a solution of chloroacetic acid (1.68 g, 17 mmol) in THF (6 mL), and benzene (90 mL). Reaction mixture was warmed to room temperature and stirred for 1 h, and compound of Example 29a (1.3 g, 2.9 mmol) was added. Reaction mixture was refluxed for 3 h. Reaction mixture was cooled and quenched using sodium bicarbonate solution, and extracted with ethylacetate. Organic layer was washed with water (100 mL) and brine (50 mL). The crude product obtained was purified by column chromatography (silica gel, ethylacetate/pet-ether) to obtain the title compound. Yield: 1.25 g (87%); 1H NMR (DMSO-d6, 300 MHz): δ 2.00 (t, 2H, CH2), 2.63 (s, 3H, CH3), 3.66 (t, 2H, CH2), 3.69-3.80 (m, 6H, 3×CH2), 3.85(s, 3H, OCH3), 5.16 (s, 2H, CH2), 6.74 (s, 1H, Ar), 6.85 (s, 1H, Ar), 8.08 (s, 1H, Ar), 8.14 (s, 1H, Ar); MS: m/e (El) 506 (M+).
