Reaction Steps

A round-bottomed flask is equipped with magnetic stirrer and charged with methylene dichloride (100 ml), (S)-3-((Methoxycarbonyl)methyl)-5-methylhexanoic acid (20 g) and with triethylamine (0.77 g) and cooled to 0-5° C. followed by addition of ethyl chloroformate (9 g). The mixture was stirred for 1-2 h at a temperature of 20° C. to 25° C., followed by quenching with 25% aqueous ammonia (100 ml). The resulted slurry is filtered and washed with water and dried to obtain a solid of (R)-methyl 3-(carbamoylmethyl)-5-methylhexanoate.
