[{"from": "human", "value": "Use the given information to create a molecule that fulfills the desired purpose. The molecule is alpha-Ergocryptine in which the isobutyl (2-methylpropyl) substituent is replaced by sec-butyl (1-methylpropyl). It is a natural ergot alkaloid. Note that ergocryptine discussed in the literature prior to 1967, when beta-ergocryptine was separated from alpha-ergocryptine, is now referred to as alpha-ergocryptine. It derives from a hydride of an ergotaman."}, {"from": "gpt", "value": "[C][C][C][Branch1][C][C][C@H1][C][=Branch1][C][=O][N][C][C][C][C@H1][Ring1][Branch1][C@][Branch2][Branch1][Branch2][N][Ring1][#Branch2][C][=Branch1][C][=O][C@][Branch1][Ring2][O][Ring1][=Branch1][Branch1][=Branch1][C][Branch1][C][C][C][N][C][=Branch1][C][=O][C@H1][C][N][Branch2][Ring1][Branch2][C@@H1][C][C][=C][N][C][=C][C][=C][C][=Branch1][=Branch1][=C][Ring1][=Branch2][Ring1][=Branch1][C][Ring1][N][=C][Ring1][S][C][O]"}]
