Procedure

Pass hydrogen sulfide, with ice cooling, into 150 ml. methanol until the weight increase amounts to 3.2 g., add thereto a solution of 370 mg. diethylamine in 11 ml. methanol and subsequently 4.8 g. 2-methyl-2-pentyl-oxirane in 18 ml. methanol, again pass hydrogen sulfide into the solution for 15 minutes, leave standing for 12 hours at room temperature, distill off the solvent, dissolve the residue in 50 ml. petroleum ether (b.p.=50°-70°), wash with water, dry over sodium sulfate and distill off the solvent to obtain as the residue, 2-hydroxy-2-methyl-heptanethiol as a colorless liquid;
