Yield	Reaction Conditions	Operation in experiment
98%	With N-Bromosuccinimide; In tetrahydrofuran; at 20℃; for 3.5h;	To a solution of S-methyl-lH-indole^-carboxylic acid ethyl ester, 3A (10.17 g, 50.03 mmol) in THF (100 mL) in a room temperature water bath was slowly added NBS (8.91 g, 50.06 mmol). The resulting solution was allowed to stir at room temperature for 3.5 h before water (800 mL) was added. The resulting mixture was allowed to stir at room temperature for 20 min and then filtered. The solid was washed with water (2 x 100 mL), dried in vacuo to provide the crude product 3B as a tan powder (13.8 g, 98percent yield). 1H NMR (500 MHz, CDC13): delta 8.91 (s, IH), 7.44 (q, J= 0.95 Hz 0.63 Hz, IH), 7.28 (d, J= 8.51 Hz, IH), 7.21 7.19 (dd, J= 1.58 Hz 8.51 Hz, IH), 4.46 (q, J= 6.94 Hz 7.25 Hz, 2H), 2.47 (s, 3H), 1.45 (t, J= 7.25 Hz, 3H).

Yield	Reaction Conditions	Operation in experiment
1%		Ethyl 5-methylindole-2-carboxylate in 1percent yield (2 steps), mp 157-158°; NMR delta(CD3SOCD3) 1.3 (t, 3H), 2.35 (s, 3H), 4.3 (q, 2H), 7.05 (m, 2H), 7.35 (m, 2H), 11.7 (bs, 1H); M/z (+) 203 (M+).
		B. 5-Methyl-1H-indole-2-carboxylic acid, ethyl ester The title A compound (2.095 g, 9.51 mmol, 1.0 eq) was dissolved in absolute ethanol (9.8 ml, 1M) and hydrochloric acid gas was bubbled through the reaction until it showed no starting material (45 minutes). The reaction solution was then concentrated, dissolved in ethyl acetate, and washed once with aqueous saturated sodium hydrogen carbonate. The organic phase was then dried over sodium sulfate, filtered through magnesium sulfate and concentrated. The residue was chromatographed on silica gel (60 g) eluding with toluene followed by chloroform:hexane (1:4) followed by ether:hexane (2:3) to give the title B compound (1.5187 g).
		b Ethyl 5-methylindole-2-carboxylate 130 g of P2 O5 are added to 111 ml of orthophosphoric acid. After cooling, 37 g of the compound from a) are added, and the mixture is heated to 80° C. After the reaction starts, the temperature rises to 130° C. The mixture is cooled and then poured into ice-water and extracted with ethyl acetate. The organic phase is washed with NaHCO3 (1N), H2 O and saturated NaCl solution, dried with Na2 SO4 and concentrated. The product is recrystallized from n-hexane/EtOAc. 11.7 g of product of melting point 158° C. are obtained.
